Context paragraphs:
Flute Sonata (Prokofiev): The Flute Sonata in D, Op. 94, was completed in the summer of 1943 by Sergei Prokofiev.  At that same time, Prokofiev was working on music for "Ivan the terrible".  The flute sonata in D was first performed in Moscow, Russia on December 7, 1943 by Nicolai Kharkovsky (flute) and Sviatoslav Richter (piano).  It was later transcribed for violin in 1944, by the composer with the help of violinist David Oistrakh, as Op. 94a.  The violin version was first performed by David Oistrakh (violin) and Lev Oborin, Piano, on June 17, 1944.

Violin Sonata No. 3 (Hill): Violin Sonata No. 3 in A minor, Stiles 1.2.1.6 So3, is a sonata for violin and piano by Alfred Hill.  Its music originates from his "Piano Trio in A minor, Stiles 1.2.2.1 TrA" (probably 1890s).  It has no precise dating, but was obviously finished after "Violin Sonata No. 2" (January 1906): most probably in 1907.  It was performed ion 6 July 1908 at the YMCA Hall in Sydney by Cyril Monk (the dedicatee of Hill's previous sonata) and Constance Brandon Usher.  Hill later arranged this sonata for flute and piano (the so-called "Flute Sonata No. 2 in A minor, Stiles 1.2.1.1 SoA2").

Flute sonata: A flute sonata is a sonata usually for flute and piano, though occasionally other accompanying instruments may be used.  Flute sonatas in the Baroque period were very often accompanied in the form of basso continuo.

Flute sonata in G major (HWV 363b): The Flute sonata in G major (HWV 363b) was composed (c. 1711–16) by George Frideric Handel in F major for the oboe, and was transposed by an unknown hand to G major, for flute and keyboard (harpsichord).  The work is also referred to as "Opus 1 No. 5", as it was first published in 1726 or slightly later by the London publisher Walsh, in an edition falsely attributed to Jeanne Roger of Amsterdam.  Other catalogues of Handel's music have referred to the work as HG xxvii,19; and HHA iv/3,28.  The sonata was originally composed as an oboe sonata in F major (HWV 363a).

Piano Sonata No. 1 (Mozart): Wolfgang Amadeus Mozart's Piano Sonata No. 1 in C major, K.  279 / 189d (1774), is a piano sonata in three movements.  It was composed when Mozart was only 18 years old and is the first of a set of his 18 piano sonata.  All but 2 of the sonatas, No. 8 in A minor and No. 14 in C minor are in a major key.  Also, the first several sonatas seem to follow the cycle of fifths, to the flat side first (No. 1 in C major, No. 2 in F major, No. 3 in B-flat major, No. 4 in E-flat major) and then to the sharp side (No. 5 in G major, No. 6 in D major).

Toccata, Adagio and Fugue in C major, BWV 564: Toccata, Adagio, and Fugue in C major (BWV 564) is an organ composition by Johann Sebastian Bach.  As is the case with most other organ works by Bach, the autograph score does not survive.  The earliest manuscript copies were probably made in 1719–1727.  The title of the piece in these copies is given, as expected of organ literature of the time, simply as "Toccata in C major" (or more precisely, "Toccata ped: ex C" in one source and "Toccata ex C♮ pedaliter", referring to the obbligato pedal part).  The piece is an early work, probably composed in the mid-to-late Weimar years, i.e. 1710–1717.  It shares some similarities with other toccatas composed around the same time, such as BWV 538, BWV 540, and others: all show the influence of concerto style and form.

Flute Sonata in C major, BWV 1033: The Sonata in C major for flute or recorder and basso continuo (BWV 1033) is a sonata in 4 movements.  It is attributed to Johann Sebastian Bach in the manuscript, which is in the hand of his son Carl Philipp Emanuel Bach and has been dated to about 1731, although scholars question the attribution

Piano Sonata in C major, D 840 (Schubert): Franz Schubert's Piano Sonata in C major D. 840, nicknamed Reliquie upon its first publication in 1861 in the mistaken belief that it had been Schubert's last work, was written in April 1825, whilst the composer was also working on the A minor sonata, D. 845 in tandem.  Schubert abandoned the C major sonata, and only the first two movements were fully completed, with the trio section of the third movement also written in full.  The minuet section of the third movement is incomplete and contains unusual harmonic changes, which suggests it was there Schubert had become disillusioned and abandoned the movement and later the sonata.  The final fourth movement is also incomplete, ending abruptly after 272 bars.

Carl Philipp Emanuel Bach: Carl Philipp Emanuel Bach (8 March 1714 – 14 December 1788), also formerly spelled Karl Philipp Emmanuel Bach, was a German Classical period musician and composer, the fifth child and second (surviving) son of Johann Sebastian Bach and Maria Barbara Bach.  His second name was given in honor of his godfather Georg Philipp Telemann, a friend of Johann Sebastian Bach.

Flute sonata in B minor (HWV 367b): The Flute sonata in B minor (HWV 367b) is a work for flute and keyboard (harpsichord), however the sonata was originally composed (c. 1712) by George Frideric Handel as a "Recorder sonata in D minor (HWV 367a)".  Other catalogues of Handel's music have referred to the work as HG xxvii,32; and HHA iv/3,42.
