Companion, for two pianos, was composed through late 2018 and early 2019, while the first notehead pencil sketches date to 2011. It is dedicated to my two youngest children. All of the material derives from seven-note rows: orderings of the pitches of the diatonic scale. The harmony resembles traditional tonality heard through a pandiatonic filter. There are four sections, divided by key signature: F major, A-flat major, B major and D major.
Each section is constructed from one or two unique, quasi-symmetrical rows that move generally by fourths and fifths. Each row is layered against itself in homorhythmic canons of up to six voices, often accompanied by high and low pedals tones which form an additional canon in augmentation. Almost every chord in Companion is the result of a basic serial process, one exception being the transition between the third and fourth sections, which features chords built from nested fifths. Ultimately, such chords result from the canons as well.
The final chord is arrived at through symmetrical voice leading from the penultimate chord, and is also the initial row spelled vertically from bottom to top. Form at the local and vertical levels is highly rationalized, while global and horizontal form—rhythmic structure and phrasing—is loosely associative.
