Over the summer of 2022, I wrote a series of twelve chorales for piano as a harmonic exercise, and I eventually orchestrated the chorales for big band for use as tuning exercises. This is the complete score and parts for the orchestrated chorales. If you would like only the piano chorales, please see "Twelve Chorales (piano only)". 
 
Instrumentation: standard plus optional Flute, Bb clarinet, F Horn, Tuba, Guitar, and Vibraphone. There is no drum set part.
