The Gnossiennes are two series of three piano pieces by the famous French composer Erik Satie. Eric Alfred Leslie Satie (Honfleur, 17 May 1866 – Paris, 1 July 1925) was a French composer and pianist. ...

The fourth gnossienne is frequently considered the most notable of the six. Composed in A Minor, it features a bass line centred around an A Major Chord VI (F) sounding D, A, D, F, A, D, F, D, A, F, D, A, D. The bass part then transposes into a C Minor Chord I ostinato following the pattern G, G, C, Eb, G, C, G, C, G, Eb, C, G, C. Section B, often considered a musically inspired section, uses semiquavers to contrast the Minor melody of Section A.

Notably, the first three Gnossienes are without time signatures or bar lines.
