Three Part Invention (No. 7) by Johann Sebastian Bach arranged for two clarinets and bass clarinet by Harry R. Gee. Cojarco Music/Kendor Music, 2010, includes parts and score. The piece is in 3/4 time marked Andante espressivo (eighth note = 92). The parts are equal and the duration is about 3 minutes. The publisher has this as (US) grade 3 piece and it is probably on the upper end of that difficulty level. (C1551)
