The collection was written June–August 1909 and consists of four volumes, the last with an epilogue. It was published later in the same year by Zimmermann of Leipzig under four separate catalog numbers (Z 4755, Z 4756, Z 4757, and Z 4781). Each book takes about five minutes to play, and may be played separately, or together as a cycle. As in many other works by Busoni, it is compiled from transcribed, freely adapted, and original music.^[1][2]

• Book 1: Preludietto, Fughetta ed Esercizio - this section uses impressionist harmonies reminiscent of Claude Debussy. In the "Esercizio", chords suggesting A major in the left hand are juxtaposed with passages in the right based on the whole tone scale.
• Book 2: Preludio, Fuga e Fuga figurata (Studie nach J. S. Bach's Wohltemperiertem Klavier) - The "Preludio" and "Fuga" are almost unaltered transcriptions of the D major prelude and fugue from the first book of Bach's Well-Tempered Clavier. The "Fuga figurata" presents elements of the prelude and fugue simultaneously.
• Book 3: Giga, Bolero e Variazione (Studie nach Mozart) - The "Giga" is based on Wolfgang Amadeus Mozart's Eine kleine Gigue, K. 574, the "Bolero" is based on the fandango in the Act III finale of The Marriage of Figaro, while the "Variazione" is a variation on the "Giga".
• Book 4: Introduzione e Capriccio (Paganinesco) & Epilogo - The "Introduzione" is a transcription of the opening of Niccolò Paganini's Caprice No. 11 for solo violin and the "Capriccio" is an arrangement of his Caprice No. 15, followed by a return of the material from the "Introduzione," but in modified and grandiose style. Busoni embellishes the originals, creating a difficult piece reminiscent of the elaborate early versions of Franz Liszt's own Paganini transcriptions.^[3] In the epilogue, music from Book 1 returns. Although, as before, the harmonic language is impressionist and tonal centres are unclear, the piece closes with a cadence in C major. (The epilogue is omitted, when the books are not played as a cycle.)

The first performance, of Books 2, 3, and 4 (without "Epilogo"), was on 16 October 1909 in Bechstein Hall, London, with Busoni as the pianist.^[4]

The materials of Book 1, and the "Epilogo," all related and highly original compositions, and written in the new style first explored in Elegien (BV 249), were later revised and combined with a new introduction and short linking passages presenting the thematic roots of the pieces and gluing them together into a single entity. The new piece, resembling a set of variations without a theme, Busoni entitled Sonatina (BV 257). This more advanced and forward-looking composition was the first of what would eventually be six "sonatinas" containing some of the most unusual and original piano music of the early 20th century.^[2][5]
