"Last Date" is a 1960 instrumental written and performed by Floyd Cramer.
 It exemplifies the "slip note" style of piano playing that Cramer made popular.
 It peaked at number 11 on the country chart and at number two on the Hot 100.
 Cramer's recording inspired a number of successful cover versions, including a vocal adaptation by Conway Twitty.
Slip jig refers to both a style within Irish music, and the Irish dance to music in slip-jig time.
 The slip jig is in time, traditionally with accents on 5 of the 9 beats — two pairs of crotchet/quaver (quarter note/eighth note) followed by a dotted crotchet note.
Harlem Stride Piano, stride piano, commonly abbreviated to stride, is a jazz piano style that was developed in the large cities of the US East Coast, mainly New York City, during the 1920s and 1930s.
 The left hand characteristically plays a four-beat pulse with a single bass note, octave, seventh or tenth interval on the first and third beats, and a chord on the second and fourth beats.
 Occasionally this pattern is reversed by placing the chord on the downbeat and bass note(s) on the upbeat.
 Unlike performers of the ragtime popularized by Scott Joplin and unlike much early jazz, stride players' left hands often leapt greater distances on the keyboard, and they played in a wider range of tempos and with a greater emphasis on improvisation.
Chet, Floyd & Boots is a studio album by American guitarist Chet Atkins, pianist Floyd Cramer and saxophone player Boots Randolph.
 Boots had a novelty hit with "Yakety Sax" which Chet covered, playing the saxophone lead on guitar, as "Yakety Axe" - which also became a hit.
 Cramer was a regular session musician at the Nashville studios, playing with a multitude of artists including Elvis Presley and Brenda Lee, helping to define the "Nashville Sound" that Atkins had also helped develop.
 The trio briefly toured together.
Einojuhani Rautavaara's six Etydit (Études), Op. 42 were composed in 1969.
 According to the composer, the intent in writing these works, each of which explores a single interval, was to "...reintroduce a sonorous, broad piano style using the entire compass of the keyboard, presenting this wonderful instrument in its full abundance."
 Matambo, in her study of the composer's solo piano works, noted that the composer also referred to the works as "interval experiments", and that with the exception of the first of the études ("Terssit ") all of the pieces exploit dissonance.
"Oh!
 You Pretty Things" is a song written by David Bowie in 1971 for the album "Hunky Dory".
 It opens with only piano and Bowie's vocal, before entering the catchy refrain.
 The simple piano style is often compared to The Beatles' "Martha My Dear".
 Thematically, the song has been seen as reflecting the influence of occultist Aleister Crowley, philosopher Friedrich Nietzsche, and Edward Bulwer-Lytton's hollow earth novel "The Coming Race", and heralding "the impending obsolescence of the human race in favour of an alliance between arriving aliens and the youth of the present society".
Erskine Butterfield (February 9, 1913 – July 11, 1961) was an American pianist, singer, bandleader and composer, active in the 1930s to the 1950s, and best known for his boogie-woogie and swing piano style.
 Butterfield was credited with "helping to invent the style of 'cocktail piano'."

 He became known for his percussive, driving piano style that concentrated on the lower octaves of the keyboard.
Floyd Cramer (October 27, 1933 – December 31, 1997) was an American Hall of Fame pianist who was one of the architects of the Nashville sound.
