                            Copyright

    The panel affirmed the district court’s order vacating a
jury’s award of damages for copyright infringement and
granting judgment as a matter of law to Katheryn Hudson
(pka Katy Perry) and other defendants.

    Christian hip-hop artists Marcus Gray (pka Flame),
Emanuel Lambert, and Chike Ojukwu claimed that an
ostinato, or repeating instrumental figure, in Hudson’s song
“Dark Horse” copied a similar ostinato in plaintiffs’ song
“Joyful Noise.”

    The panel held that copyright law protects musical works
only to the extent that they are “original works of
authorship.” The panel concluded that the ostinatos at issue
here consisted entirely of commonplace musical elements,
and the similarities between them did not arise out of an
original combination of these elements. Consequently, the
jury’s verdict finding defendants liable for copyright
infringement was unsupported by the evidence because
plaintiffs failed to put forward legally sufficient evidence

works with respect to any musical features protectible under

                        OPINION

M. SMITH, Circuit Judge:

    Plaintiffs Marcus Gray (pka Flame), Emanuel Lambert,
and Chike Ojukwu are Christian hip-hop artists who have
sued Katheryn Hudson (pka Katy Perry), Capitol Records
LLC, and several other defendants for copyright
infringement. They claim that a repeating instrumental
figure—in musical terms, an ostinato—in Hudson’s song
“Dark Horse” copied a similar ostinato in plaintiffs’ song
“Joyful Noise.” After a trial centering around the testimony
of musical experts, a jury found defendants liable for
copyright infringement and awarded $2.8 million in
damages. The district court vacated the jury award and
granted judgment as a matter of law to defendants,
concluding principally that the evidence at trial was legally
insufficient to show that the Joyful Noise ostinato was
copyrightable original expression.
                         GRAY V. HUDSON                               5

    We affirm. Copyright law protects “musical works”
only to the extent that they are “original works of
authorship.” 17 U.S.C. § 102(a). The trial record compels
us to conclude that the ostinatos at issue here consist entirely
of commonplace musical elements, and that the similarities
between them do not arise out of an original combination of
these elements. Consequently, the jury’s verdict finding
defendants liable for copyright infringement was
unsupported by the evidence. 1

                        BACKGROUND

I. Musical Background

    We begin by briefly explaining some vocabulary that we
rely on throughout this opinion. A musical scale is
essentially a sequence of musical notes or tones ordered by
pitch (i.e., how “low” or “high” each note is). To illustrate
this concept, a standard piano or keyboard instrument has
white and black keys organized in a twelve-key repeating
pattern. If one starts with any key on the piano and plays
twelve white and black keys in order from left to right, she
will have played all the notes of the “chromatic” scale in
ascending order. That ordered sequence of twelve notes—
which repeats itself at higher and lower registers across the
    1
       We accept the amicus briefs submitted by (1) the Recording
Industry Association of America and the National Music Publishers’
Association, (2) the Motion Picture Association, (3) a group of 110
individual songwriters and other music industry professionals, along
with Nashville Songwriters Association International and Music Arts
Coalition, and (4) a group of musicologists. See Dkt. Nos. 51, 54, 56,
58. We deny as moot defendants’ motion to strike material from
plaintiffs’ opening brief, Dkt. No. 29, because we conclude that even if
we were to consider the purportedly improper material, we would still
decide this case in defendants’ favor for the same reasons given in this
opinion.

keyboard—can be thought of as the musical equivalent of an
artist’s coloring palette, as one can rearrange these notes into
more complex sequences and add rhythmic (i.e., durational)
variety to create memorable tunes.

    In practice, many songs are based on scales that use only
a smaller subset of the twelve notes in the chromatic scale.
These scales have different names depending on which notes
are chosen. The scale we are primarily concerned with today
has seven notes and is called the “minor” scale. 2

     As with other scales, the notes in the minor scale can be
referred to with alphabetic names (A, B, C, etc.), but the
parties have generally opted to refer to them with numerical
degrees indicating each note’s ordered position in the scale.
We agree that is the more convenient approach here. The
image below, taken from the beginning of defendants’
answering brief, illustrates how numerical scale degrees
correspond to different keys on a piano in the minor scale 3
(the image begins with the third note of the scale on the far
left rather than the first note—as discussed, the notes on a
piano repeat themselves every twelve keys in different pitch
registers):

    2
       Our discussion here is slightly oversimplified, as the minor scale
comes in three distinct forms. However, the differences between those
versions are not material to resolving this case. Likewise, we do not find
it necessary for present purposes to distinguish between the concept of a
“scale” and the related concept of a “mode,” which is also mentioned in
the parties’ briefing.
     3
       Specifically, the image corresponds to the natural minor scale in
the key of A, which uses only the white keys on a keyboard.
                     GRAY V. HUDSON                         7

II. Factual Background

    In 2007, plaintiff Ojukwu recorded a simple tune using a
free music website. He later sold it to plaintiff Gray, who
used it as an ostinato (i.e., a repeating musical figure) for
Joyful Noise. A recording of Joyful Noise first appeared in
the album Our World Redeemed in 2008. While Joyful
Noise did not achieve significant commercial success or
playtime on the radio, it received millions of views on
YouTube and Gray’s MySpace page. Our World Redeemed
was also nominated for a Grammy award in the “Best Rock
or Rap Gospel Album” category in 2009.

    Defendants created Dark Horse in 2013. Hudson’s trial
testimony was that she met with two of her co-defendants at
a recording studio and sampled several short musical
fragments to consider using in a new song. The segment
Hudson responded to most positively became the ostinato for
Dark Horse. Dark Horse was first released on the album
Prism along with several other tracks. It was a hit, resulting
in a music video and a performance by Hudson at the Super
Bowl halftime show in 2015.

    The following features of the two ostinatos are
undisputed. Both ostinatos are based on the minor scale
(although they are in different keys, meaning that they treat
8                     GRAY V. HUDSON

different notes—i.e., keys on a piano—as the first note of the
scale). The Dark Horse ostinato is made up of eight notes
(sixteen, when repeated) which correspond to the minor
scale degrees 3-3-3-3-2-2-1-5, while the Joyful Noise
ostinato is made up of two slightly different eight-note
figures (sixteen notes when combined) that correspond to the
minor scale degrees 3-3-3-3-2-2-2-1/6 (in other words, 3-3-
3-3-2-2-2-1 for the first eight notes, and 3-3-3-3-2-2-2-6 for
the second eight notes). So, while each eight-note pattern
begins with 3-3-3-3-2-2, they differ in the last two notes.
Leaving aside some stylistic embellishment in Joyful Noise
(specifically, the use of portamento, or “sliding” between
different notes), both ostinatos also rely on a completely
uniform rhythm, meaning each note is of equal duration in
time.

III.   Trial Proceedings

     Plaintiffs filed their operative complaint for copyright
infringement against Hudson and her co-defendants in
November 2016. The case proceeded to a bifurcated jury
trial taking place from July 17, 2019, to August 1, 2019, with
separate phases to determine liability and damages. Rather
than putting forward direct evidence that defendants had
copied elements of Joyful Noise, plaintiffs focused on
circumstantial evidence that defendants had a reasonable
opportunity to access Joyful Noise and that the ostinatos in
both songs were substantially similar. For the latter point, in
addition to testimony from Hudson and other witnesses, the
liability phase of the trial turned largely on testimony by
plaintiffs’ expert musicologist, Dr. Todd Decker.

   The heart of Dr. Decker’s testimony concerned which
specific elements of the ostinatos in Dark Horse and Joyful
Noise were similar. Dr. Decker testified that:
                          GRAY V. HUDSON                                 9

         The length of [each] ostinato is similar, eight
         notes. The rhythm of the ostinato is similar.
         The melodic content, the scale degrees
         present. The melodic shape so the—the way
         the melody moves through musical space.
         Similar, the [timbre] or the quality and color
         of the sound is similar, and the use of the—
         the placement of this material, this ostinato,
         in the musical space of the recording in the
         mix[,] that is also similar. So that’s five or
         six points of similarity between the two
         ostinatos.[ 4]

However, Dr. Decker also said that there was “no one single
. . . element” that caused him to believe the ostinatos at issue
were “substantially similar” when viewed “in isolation.”
Rather, while “[a]ny single one of those [elements] would
not have been enough,” it was “the combination of them”
that led Dr. Decker to conclude that Joyful Noise and Dark
Horse had substantially similar ostinatos. He also admitted
that the ostinatos were different in some respects, though he
clarified that he did not think this negated the similarities
between them.

    The jury also heard testimony from defendants’ expert,
Dr. Lawrence Ferrara, who disagreed with Dr. Decker’s
assessment that the ostinatos were substantially similar. He
noted the use of different scale degrees at the end of each
ostinato, pointing out that Dark Horse has a “leap” from 1 to
5 while Joyful Noise uses “step-wise” motion from 2 to 1 at
the corresponding point in time. In addition, Dr. Ferrara
explained that two well-known songs—“Jolly Old Saint

    4
      Dr. Decker also testified that the ostinatos in Joyful Noise and Dark
Horse both used notes that were rhythmically “even in value.”
10                    GRAY V. HUDSON

Nicholas” and “Merrily We Roll Along” (which, as Dr.
Ferrara noted, has the same tune as “Mary Had a Little
Lamb”)—also use the 3-3-3-3-2-2 pitch sequence that the
Dark Horse and Joyful Noise ostinatos share (or a similar 3-
3-3-2-2 sequence for Merrily We Roll Along, with the third
3 doubled in duration). This testimony was not refuted
(though Dr. Decker dismissed its importance to the
similarity inquiry), nor was Dr. Ferrara’s testimony that
three other pieces of music predating Joyful Noise also used
pitch progressions proceeding from 3 to 2 to 1 played in an
even rhythm: “Love Me Or Hate Me” (which was composed
by defendant Lukasz Gottwald, pka Dr. Luke), “Brainchild,”
and “Choosing Life.”

    For each phase of the trial, the jury was instructed on the
law and given a special verdict form. Among other
conclusions, the jury found specifically that Dark Horse used
protected material from Joyful Noise, that the two songs
contained substantially similar copyrightable expression,
that defendants had a reasonable opportunity to hear Joyful
Noise before composing Dark Horse, and that plaintiffs were
entitled to 22.5% of defendants’ net profits from Dark Horse,
resulting in a total verdict of about $2.8 million in damages.

IV.    Post-Trial Motions

    After the trial, defendants moved for judgment as a
matter of law (JMOL) or, alternatively, for a new trial
pursuant to Federal Rule of Civil Procedure 50(b). Plaintiffs
also moved for an award of prejudgment interest. The
district court considered these motions simultaneously.

    The district court vacated the jury’s verdict and granted
defendants’ JMOL motion. It denied the parties’ remaining
motions as moot, but conditionally granted a new trial and
denied prejudgment interest in the alternative. See Fed. R.
                     GRAY V. HUDSON                        11

Civ. P. 50(c) (allowing this procedure). As relevant here, the
district court’s 32-page decision rejected all of defendants’
challenges to the jury verdict except their argument that the
ostinatos were not substantially similar. Citing Dr. Decker’s
testimony, the district court reasoned that none of the
individual points of similarity the expert identified between
Dark Horse and Joyful Noise constituted copyrightable
original expression. The district court also did not believe
that the combination of these elements constituted original
expression. Alternatively, the district court concluded that
this combination merited no more than a “thin” copyright,
which is infringed only by “virtually identical” works. The
district court determined that there were enough objective
distinctions between the ostinatos such that they were not
virtually identical.

    Plaintiffs timely appealed. We review de novo the
district court’s grant of JMOL. Zamalloa v. Hart, 31 F.3d
911, 913 (9th Cir. 1994).

                        ANALYSIS

    The operative question is whether a “reasonable jury”
would have had “a legally sufficient evidentiary basis” to
conclude that defendants engaged in copyright infringement.
Fed. R. Civ. P. 50(a)(1). The applicable standards are
essentially “the same” as those for a summary judgment
motion, Reeves v. Sanderson Plumbing Prods., Inc., 530
U.S. 133, 150 (2000) (quoting Anderson v. Liberty Lobby,
Inc., 477 U.S. 242, 251 (1986)), meaning that we “must draw
all reasonable inferences” in plaintiffs’ favor, id. Along
these lines, we “must disregard all evidence favorable to
[defendants] that the jury is not required to believe,” but we
should also “give credence to . . . evidence supporting
[defendants] that is uncontradicted and unimpeached, at least
12                   GRAY V. HUDSON

to the extent that that evidence comes from disinterested
witnesses.” Id. at 151 (cleaned up).

    Copyright protection extends only to works that contain
original expression. 17 U.S.C. § 102(a); Feist Publ’ns, Inc.
v. Rural Tel. Serv. Co., 499 U.S. 340, 345 (1991). “Original,
as the term is used in copyright, means only that the work
was independently created by the author . . . and that it
possesses at least some minimal degree of creativity.” Feist,
499 U.S. at 345. “To establish [copyright] infringement, two
elements must be proven: (1) ownership of a valid copyright,
and (2) copying of constituent elements of the work that are
original.” Id. at 361 (emphasis added).

    We agree with the district court that plaintiffs failed to
establish copying of any original—and, consequently,
protected—elements of Joyful Noise. For that reason, we
affirm its decision to vacate the jury award and grant JMOL
to defendants. We need not reach any other issue in this
case.

I. Legal Framework for Copyright Infringement

    Because plaintiffs did not present any direct evidence
that defendants copied Joyful Noise’s ostinato, they were
required to show that (1) defendants had “access” to their
work and (2) the ostinatos in Joyful Noise and Dark Horse
“are substantially similar.” L.A. Printex Indus., Inc. v.
Aeropostale, Inc., 676 F.3d 841, 846 (9th Cir. 2012),
abrogated on other grounds as recognized by Unicolors, Inc.
v. H&M Hennes & Mauritz, L.P., 959 F.3d 1194, 1198 (9th
Cir. 2020); see also Apple Computer, Inc. v. Microsoft
Corp., 35 F.3d 1435, 1442 (9th Cir. 1994) (copying may be
shown through “circumstantial evidence of access and
substantial similarity”). We need not address the access
prong because we may resolve this case based on the
                     GRAY V. HUDSON                        13

“substantially similar” prong. For that requirement, we have
“traditionally determined whether copying sufficient to
constitute infringement has taken place under a two-part test
having ‘extrinsic’ and ‘intrinsic’ components.” Apple, 35
F.3d at 1442. “Both tests must be satisfied for the works to
be deemed substantially similar.” Skidmore as Tr. for Randy
Craig Wolfe Tr. v. Led Zeppelin, 952 F.3d 1051, 1064 (9th
Cir. 2020) (en banc).

    “The extrinsic test considers whether two works share a
similarity of ideas and expression as measured by external,
objective criteria. The extrinsic test requires . . . breaking
the works down into their constituent elements, and
comparing those elements for proof of copying as measured
by substantial similarity. Because the requirement is one of
substantial similarity to protected elements of the
copyrighted work, it is essential to distinguish between the
protected and unprotected material in a plaintiff’s work.”
Swirsky v. Carey, 376 F.3d 841, 845 (9th Cir. 2004) (cleaned
up); accord Skidmore, 952 F.3d at 1064. The intrinsic test
focuses on “similarity of expression from the standpoint of
the ordinary reasonable observer, with no expert assistance.”
Apple, 35 F.3d at 1442.

    At oral argument and in their briefing, plaintiffs argued
that we are required to defer to the jury’s determination that
the Joyful Noise and Dark Horse ostinatos are substantially
similar. But even when juries serve as the factfinders, judges
retain an important gatekeeping role in applying the law. To
be sure, the intrinsic test for substantial similarity is
“uniquely suited for determination by the trier of fact”
because of its focus on the lay listener, and so “this court
must be reluctant to reverse” a jury’s finding that two works
are intrinsically similar. Sid & Marty Krofft Television
Prods., Inc. v. McDonald’s Corp., 562 F.2d 1157, 1166 (9th
14                        GRAY V. HUDSON

Cir. 1977), overruled on other grounds by Skidmore, 952
F.3d 1051; 5 accord Three Boys Music Corp. v. Bolton, 212
F.3d 477, 485 (9th Cir. 2000), overruled on other grounds
by Skidmore, 952 F.3d 1051 (quoting same, and adding, “We
will not second-guess the jury’s application of the intrinsic
test.”). Crucially, however, the extrinsic test is objective and
is often resolved as a matter of law. See Benay v. Warner
Bros. Ent., 607 F.3d 620, 624 (9th Cir. 2010), overruled on
other grounds by Skidmore, 952 F.3d 1051 (noting summary
judgment is often granted on this issue). So, while we must
refrain from usurping the jury’s traditional role of evaluating
witness credibility and weighing the evidence, the extrinsic
test requires us as a court to ensure that whatever objective
similarities the evidence establishes between two works are
legally sufficient to serve as the basis of a copyright
infringement claim regardless of the jury’s views.

II. Protected Elements Contained in Joyful Noise

    Because the extrinsic test for substantial similarity
requires us to distinguish between “protected and
unprotected material in a plaintiff’s work,” Swirsky, 376
F.3d at 845, the threshold issue is what—if anything—about
the Joyful Noise ostinato qualifies as original expression that
can serve as the basis for a copyright infringement claim.
See Feist, 499 U.S. at 361 (infringement requires “copying
of constituent elements of [a] work that are original”);
Skidmore, 952 F.3d at 1070 (substantial similarity test

     5
       This case and others cited in this opinion with the same subsequent
procedural history indication were overruled by Skidmore only to the
extent they suggested that a weaker showing of substantial similarity is
required when a high degree of access to a copyrighted work has been
shown. See Skidmore, 952 F.3d at 1065–69 (calling this the “inverse-
ratio rule”). These cases otherwise remain binding on us.
                      GRAY V. HUDSON                        15

focuses on “the protectible elements, standing alone, . . . and
disregard[s] the non-protectible elements” (cleaned up)).

    “Although copyright protects only original expression, it
is not difficult to meet the famously low bar for originality.”
Skidmore, 952 F.3d at 1069. “[T]he requisite level of
creativity is extremely low; even a slight amount will suffice.
The vast majority of works make the grade quite easily, as
they possess some creative spark, no matter how crude,
humble or obvious it might be.” Feist, 499 U.S. at 345
(citation and internal quotation marks omitted).

    But “[e]ven in the face of this low threshold, copyright
does require at least a modicum of creativity and does not
protect every aspect of a work; ideas, concepts, and common
elements are excluded. Nor does copyright extend to
common or trite musical elements, or commonplace
elements that are firmly rooted in the genre’s tradition. These
building blocks belong in the public domain and cannot be
exclusively appropriated by any particular author.”
Skidmore, 952 F.3d at 1069 (cleaned up); see also Swirsky,
376 F.3d at 850 (“Under the scenes a faire doctrine, when
certain commonplace expressions are indispensable and
naturally associated with the treatment of a given idea, those
expressions are treated like ideas and therefore not protected
by copyright.”).

    The trial record here requires us to conclude that no
single point of similarity between Joyful Noise and Dark
Horse arises out of a protectible form of expression. For this
issue, it is arguably sufficient that plaintiffs’ expert
musicologist, Dr. Decker, candidly testified that “[a]ny
single one of those [elements] would not have been enough”
for him to conclude that substantial similarity existed, and
that only “the combination” of those elements led him to this
conclusion. Nonetheless, Dr. Decker testified as an expert
16                    GRAY V. HUDSON

musicologist, not as an expert on copyright law. For that
reason, we provide a brief overview of the individual
musical elements identified by plaintiffs as original, and
explain why those elements are not individually entitled to
copyright protection. We address whether copyright law
protects the combination of these unprotectible elements in
the next section.

   To reiterate, Dr. Decker drew attention to the following
musical elements in support of his opinion that the Joyful
Noise and Dark Horse ostinatos are substantially similar:

       The length of [each] ostinato is similar, eight
       notes. The rhythm of the ostinato is similar.
       The melodic content, the scale degrees
       present. The melodic shape so the—the way
       the melody moves through musical space.
       Similar, the [timbre] or the quality and color
       of the sound is similar, and the use of the—
       the placement of this material, this ostinato,
       in the musical space of the recording in the
       mix[,] that is also similar. So that’s five or
       six points of similarity between the two
       ostinatos.

Though it used slightly different terminology, plaintiffs’
opening brief focused on essentially the same musical
elements, adding that both ostinatos were based on the minor
scale.

     The evidence at trial was legally insufficient to establish
that these musical elements are individually copyrightable.
We note that Dr. Decker himself acknowledged that many of
these elements are commonplace in the musical world, even
if some aspects of the Joyful Noise and Dark Horse ostinatos
were unusual for their respective genres. For example, apart

from conceding that “there are many” songs “predating the
creation of Joyful Noise that have ostinatos,” Dr. Decker
explained that it is “characteristic” for musical phrases
playing a role similar to the ostinatos at issue here “to last
for eight beats.” And while Dr. Decker opined that it is
uncommon to use completely even rhythms in popular
music, he also testified that the use of such a rhythm in Joyful
Noise and Dark Horse was a “relatively simple rhythmic
choice” that “no composer’s entitled to monopolize.” 6
Plaintiffs adduced no evidence at trial contradicting their
own expert’s testimony suggesting that these shared
elements of the two ostinatos are merely common musical
“building blocks” belonging to the public domain. See
Skidmore, 952 F.3d at 1069; Swirsky, 376 F.3d at 850.

     Even leaving aside these admissions, our precedents and
other persuasive decisions make clear that no element
identified by plaintiffs or Dr. Decker is individually
copyrightable. Plainly, no person may copyright the minor
scale, as such scales are common musical building blocks
belonging to the public. See Skidmore, 952 F.3d at 1070–
71. The fact that Joyful Noise and Dark Horse both make
use of “sequence[s] of eight notes” played in an even rhythm
is a similarly “trite” musical choice outside the protection of
copyright law. Darrell v. Joe Morris Music Co., 113 F.2d
80, 80 (2d Cir. 1940) (per curiam). Along somewhat
different lines, the fact that Joyful Noise and Dark Horse
arguably have similar textures 7 is far too abstract of a

       Plaintiffs conceded this element was not individually protectible in

    7
      Dr. Decker explained that texture refers to the way different
musical elements—such as parts played by different instruments—are
mixed together. He commented that both Joyful Noise and Dark Horse

similarity to be legally cognizable. See Harper & Row
Publishers, Inc. v. Nation Enters., 471 U.S. 539, 556 (1985)
(explaining that copyright law protects expression, not
ideas); cf. Morrill v. Stefani, 338 F. Supp. 3d 1051, 1060
(C.D. Cal. 2018) (“the use of a long-short-long rhythm is too
general to be protectable”).

    Dr. Decker’s remark that the ostinatos have a similar
timbre also does not help plaintiffs. Dr. Decker explained
that timbre is a way of describing a sound’s quality: for
example, a clarinet and a piano playing the same notes will
sound noticeably different. Dr. Decker testified that the
synthesizers used to play the Joyful Noise and Dark Horse
ostinatos have similar timbres because they both use sounds
that are “artificial,” are in a “high” register, and seem
“pingy,” among other similar descriptors. But a copyright to
a musical work does not give one the right to assert
ownership over the sound of a synthesizer any more than the
sound of a trombone or a banjo.

    For one, plaintiffs have sued only for infringement of
their copyright in Joyful Noise as a musical composition. In
contrast, the choice of a particular instrument (whether
acoustic or electronic) to play a tune relates to the
performance or recording of a work, which are protected by
distinct copyrights. See, e.g., Williams v. Gaye, 895 F.3d
1106, 1121 (9th Cir. 2018) (“It is well settled that sound
recordings and musical compositions are separate works
with their own distinct copyrights.” (cleaned up)); Newton v.
Diamond, 204 F. Supp. 2d 1244, 1258 (C.D. Cal. 2002),
aff’d, 388 F.3d 1189 (9th Cir. 2004) (distinguishing between
“elements protected by [the plaintiff’s] copyright over the

musical composition” at issue and “those attributable to his
performance of the piece or the sound recording”).

    More generally, the use of synthesizers to accompany
vocal performers has long been commonplace in popular
music. See, e.g., Batiste v. Najm, 28 F. Supp. 3d 595, 623
(E.D. La. 2014). Along these lines, Dr. Decker conceded
that timbre “is one of the very difficult things to
monopolize.”

    That leaves us with plaintiffs’ contention that the pitch
sequence utilized by the Joyful Noise ostinato is
copyrightable, and with Dr. Decker’s related comments that
the two ostinatos use similar “scale degrees” and have the
same “melodic content [and] shape.” At this point, it is
necessary to distinguish between an abstract sequence of
pitches and a melody (or, more colloquially, a tune). Though
the concepts are sometimes equated, creating a melody
involves more than writing down a sequence of pitches; at a
minimum, that sequence must also be “rhythmically
organized” so as to form an “esthetic whole.” Melody,
Webster’s Third New International Dictionary (2002); cf.
Swirsky, 376 F.3d at 848 (distinguishing between non-
copyrightable “chord progressions” standing alone and a
copyrightable “chorus,” which involves these progressions
“in combination with rhythm and pitch sequence[s]”).
While an eight-note melody may be copyrightable, the
abstract eight-note pitch sequence that is a component of the
melody is not. See U.S. Copyright Office, Compendium of
U.S. Copyright Office Practices § 313.4(C) (3d ed. 2021)8

    8
      Available at https://www.copyright.gov/comp3/chap300/ch300-
copyrightable-authorship.pdf.  Our court has drawn upon the
Compendium for guidance on what qualifies as copyrightable
expression. See Skidmore, 952 F.3d at 1070–71. The Supreme Court
20                       GRAY V. HUDSON

(citing 37 C.F.R. § 202.1(a)) (advising that “short musical
phrases consisting of only a few musical notes standing
alone are not copyrightable . . . even if the phrase is novel or
distinctive,” and giving an eight-note pitch sequence as an
example).

    We note that this conclusion is consistent with the rule
that “chord progressions may not be individually protected”
because they are basic musical building blocks. Swirsky,
376 F.3d at 848. Chords are ultimately just a combination
of pitches played simultaneously, Skidmore, 952 F.3d at
1070, so a chord progression itself consists of multiple pitch
sequences playing out at the same time. If the chord
progression cannot be protected, the individual pitch
sequences forming the progression cannot be either.

    Turning finally to the ostinatos’ “melodic shape,” Dr.
Decker described this as “the way the melody moves through
musical space.” He explained that “scale degrees have in
them tendencies . . . . There are scale degrees that want to
go somewhere . . . and scale degrees that say you’re home
like 1.” Later in his testimony, he elaborated that “3 wants
to go to 2, [and] the 2 wants to go to 1 because 1 is our home
note.” Applying this concept to the Joyful Noise and Dark
Horse ostinatos, he testified that the repetition of scale
degree 3 in both songs created “tension that wants to be
released and it’s released to [scale degree 2] on a particularly
strong beat.”

   As with musical texture, it could be argued that the
overall “shape” of a melody as described by Dr. Decker is
nothing more than an abstraction outside the protection of

copyright law. See Harper & Row, 471 U.S. at 556. In any
event, as the district court recognized, Dr. Decker’s
explanation that the two ostinatos moved “through musical
space” in similar ways simply reflects “rules of consonance
common in popular music.” Just as films often rely on tropes
to tell a compelling story, music uses standard tools to build
and resolve dramatic tension. In this vein, courts have
recognized that “while there are an enormous number of
possible permutations of the musical notes of the scale, only
a few are pleasing.” Darrell, 113 F.2d at 80; see also
Skidmore, 952 F.3d at 1079–80 (Watford, J., concurring)
(recognizing “the constraints of particular musical
conventions and styles”). This is also underscored by the
fact that uncontradicted evidence at trial showed that two
songs predating Joyful Noise—Merrily We Roll Along and
Jolly Old Saint Nicholas—used the same pitch sequence
(albeit in the “major” scale rather than the minor scale) and
melodic shape. Cf. Granite Music Corp. v. United Artists
Corp., 532 F.2d 718, 720 (9th Cir. 1976) (“Evidence of
similar musical phrases appearing in prior works . . .
demonstrates that the musical language was of such ordinary
and common occurrence that the probability of independent,
coincidental production was great.”).

    Because the use of similar pitch sequences in the Joyful
Noise and Dark Horse ostinatos results only from the use of
commonplace, unoriginal musical principles, it cannot be the
basis for a copyright infringement claim on its own. See
Swirsky, 376 F.3d at 850 (expression that is “naturally
associated with the treatment of a given idea” is not
copyrightable).

III.    Protection of the Unprotectible Musical Elements
        in Combination

    Although no individual musical component of the Joyful
Noise ostinato is copyrightable, we still must consider
whether the Joyful Noise ostinato is protectible as a
“combination of unprotectable elements.” Satava v. Lowry,
323 F.3d 805, 811 (9th Cir. 2003); see also Swirsky, 376 F.3d
at 848 (“[A] substantial similarity can be found in a
combination of elements, even if those elements are
individually unprotected.”). That is the case only if the
“selection and arrangement” of those elements is original in
some way. Satava, 323 F.3d at 811.

     We begin this analysis with some guiding principles. To
start, the fact that the ostinatos here are only eight notes long
does not foreclose the possibility of a protected arrangement
of commonplace musical elements. See Swirsky, 376 F.3d
at 852 (“It cannot be said as a matter of law that seven notes
is too short a length to garner copyright protection.”). “Each
note in a scale . . . is not protectable, but a pattern of notes in
a tune may earn copyright protection.” Metcalf v. Bochco,
294 F.3d 1069, 1074 (9th Cir. 2002), overruled on other
grounds by Skidmore, 952 F.3d 1051 (emphasis added). On
the other hand, despite “the famously low bar for
originality,” Skidmore, 952 F.3d at 1069, “[t]rivial elements
of compilation and arrangement . . . fall below the threshold
of originality.” United States v. Hamilton, 583 F.2d 448, 451
(9th Cir. 1978); accord Satava, 323 F.3d at 811–12.

    One circumstance where an arrangement of individual
elements lacks enough creativity to garner copyright
protection is when that arrangement is “practically
inevitable” or in keeping with “an age-old practice, firmly
rooted in tradition and so commonplace that it has come to
be expected as a matter of course.” Feist, 499 U.S. at 363.
                     GRAY V. HUDSON                        23

“For example, it is well-settled that copyright of a map does
not give the author an exclusive right to the coloring,
symbols, and key used in delineating boundaries of and
locations within the territory depicted.” Hamilton, 583 F.2d
at 451 (9th Cir. 1978). The same is true for an alphabetical
arrangement of numbers in a phonebook. Feist, 499 U.S. at
363. These are all utterly conventional ways of arranging
information, and so they cannot be called “original” under
copyright law.

    To provide an example in the artistic context, we have
held that lifelike glass “jellyfish sculptures” enclosed in a
clear outer layer of glass did not combine public-domain
elements in an original way. Satava, 323 F.3d at 811. We
did not dispute that the sculptures were “beautiful,” but we
determined that elements such as the “selection of clear
glass, oblong shroud, bright colors, proportion, vertical
orientation, and stereotyped jellyfish form, considered
together, lack[ed] the quantum of originality needed to merit
copyright protection.” Id. This was because “[t]hese
elements are so commonplace in glass-in-glass sculpture and
so typical of jellyfish physiology that to recognize copyright
protection in their combination effectively would give [the
artist] a monopoly” over this artform. Id. at 812.

    Likewise, the portion of the Joyful Noise ostinato that
overlaps with the Dark Horse ostinato consists of a
manifestly conventional arrangement of musical building
blocks. Joyful Noise and Dark Horse contain similar
arrangements of basic musical features mainly in that both
employ the pitch progression 3-3-3-3-2-2 played in a
completely flat rhythm. This combination is unoriginal
because it is really nothing more than a two-note snippet of
a descending minor scale, with some notes repeated. See
Skidmore, 952 F.3d at 1070 (holding that descending scales
24                       GRAY V. HUDSON

are not copyrightable). Allowing a copyright over this
material would essentially amount to allowing an improper
monopoly over two-note pitch sequences or even the minor
scale itself, especially in light of the limited number of
expressive choices available when it comes to an eight-note
repeated musical figure. See Satava, 323 F.3d at 812 & n.5
(expressing concerns over monopolization when limited
creative choices are available); see also Skidmore, 952 F.3d
at 1079–80 (Watford, J., concurring) (“There are relatively
few ways to express a combination of five basic elements in
just four measures, especially given the constraints of
particular musical conventions and styles . . . . [O]nce [the
artist] settled on using a descending chromatic scale in A
minor, there were a limited number of chord progressions
that could reasonably accompany that bass line (while still
sounding pleasant to the ear).”); Calhoun v. Lillenas Publ’g,
298 F.3d 1228, 1232 (11th Cir. 2002) (per curiam)
(recognizing “the limited number of musical notes (as
opposed to words in a language), the combination of those
notes[,] and their phrasing”); Darrell, 113 F.2d at 80.

    Consequently, insofar as it combines musical building
blocks in the same way that the Dark Horse ostinato does,
the Joyful Noise ostinato lacks “the quantum of originality
needed to merit copyright protection.” Satava, 323 F.3d at
811. If we were to hold otherwise, “it is hard to believe that
any collection” of pitches arranged in a flat rhythm “could
fail” to meet the originality threshold. Feist, 499 U.S. at
364–65 (recognizing that “some works must fail” the
originality requirement). 9

     As in Satava, we certainly do not suggest that Joyful Noise as a
     9

whole is lacking in original expression. See 323 F.3d at 812 (“We do not
mean to suggest that [the artist] has added nothing copyrightable to his
                          GRAY V. HUDSON                              25

IV.      Plaintiffs’ Remaining Arguments

     Two other issues warrant brief commentary. First,
plaintiffs’ opening brief contended that the district court
improperly relied on evidence outside the record submitted
by amici after trial, namely amici’s representation that they
had found many tunes similar to the ostinatos at issue here
in musical databases. Why that might be relevant to our de
novo review is not entirely clear, as neither defendants nor
amici have brought this material to our attention on appeal.
Regardless, the district court referred to this material only in
a single “see also” cite following a lengthy string cite to the
trial record. Striking this from the court’s order would have
no noticeable effect on its thorough 32-page analysis.

    Second, we reject plaintiffs’ suggestion that it was
improper for the district court to grant JMOL after
previously having denied summary judgment on the issue of
extrinsic similarity, which is unsupported by any authority.
A trial judge has had the benefit of hearing testimony and a
full presentation of the evidence when ruling on a post-trial
JMOL motion, which may occasionally give her new
insights into the legal sufficiency of the evidence. See, e.g.,
Lies v. Farrell Lines, Inc., 641 F.2d 765, 772 (9th Cir. 1981).
While JMOL and summary judgment are procedurally
similar, there is no rule preventing a trial judge from
reconsidering her views on a case’s merits.

jellyfish sculptures.”). But once we “disregard the non-protectible
elements” in Joyful Noise, Skidmore, 952 F.3d at 1070, we are left with
no objective similarities between Joyful Noise and Dark Horse that may
serve as the basis for plaintiffs’ copyright claims, see, e.g., Benay, 607
F.3d at 624 (extrinsic test requires “articulable similarities” between
works).
26                  GRAY V. HUDSON

                     CONCLUSION

    Plaintiffs failed to put forward legally sufficient
evidence that Joyful Noise and Dark Horse are extrinsically
similar works with respect to any musical features
protectible under copyright law. Consequently, we affirm
the district court’s order vacating the jury award and
granting JMOL to defendants.

     AFFIRMED.
