Contrapunctus 1, from Art of the Fugue, BWV.1080 (Dishinger) [bass clef]
Baroque period. First movement (BWV 1080, Nr 1) of Bach's final opus. Originally written in 4-part SATB open score form, and now believed to have been intended for performance on the harpsichord, here in an interesting transcription for solo euphonium & piano. --cdp
