Composition 2022.04 (Morton Feldman) is based on the pitches and pitch sequences from Morton Feldman’s Trio for Flutes (1972). For the construction of his composition Feldman used cells made from a small number of pitches - with the cells sometimes being repeated - and sometimes using the same notes - but in different octaves.
These are all the tones that Feldman used in his composition - all of which are included in Composition 2022.04: C#2 - D2 - D#2 - E♭2 - E2 - F2 - G♭2 - A♭2 - C#3 - D3 - E♭3 - E3 - F3 - G♭3 - G3. And here are three examples of the cells: C#2 - E♭2 - D2 / C#3 - E♭3 - D3 / E3 - F3 - G♭3. (C2 equals Middle-C).
