"Patterns" is a piece originally written for 16 brass, but was rewritten for any 16 instruments, and is now a quintet.
It starts out with an introduction of a choral in D Dorian. Then a melody of this choral is phased between the upper and lower parts until it repeats. This phasing is repeated one more time, but with the upper instruments coming down a note every two repeats and the bottom instruments coming up a note every two repeats. Very interesting chords and harmonies result from the phasing. The phasing resolves and the piece ends in a full choral. The piece is heavy with triples and changing meter. Parts are included for most any instruments: C, Bb, Eb, and F. An interesting option would be tuned percussion - celeste, vibes, marimba, or timpani
For Bb and Eb instruments, Parts 1 through 3 are written for smaller instruments with a transposition of a second. Parts 4 through 5 are written for larger instruments with a transposition of a second plus an octave.
