Air on the G String, from Orchestral Suite No 3 in D, BWV.1068 (McCarty)
Baroque. Bach's popular Air on the G String here arranged for quartet. The bass trombone performs the moving bass line while the three tenors realize the upper string parts. The three tenor parts are notated in two stave systems (much like a duet). Each stave has different breathing/phrasing indicated. This has been done so that a performance with doubled parts can have no breathing gaps. Score & parts.
