Baroque. The Italian Concerto, BWV 971 was composed in 1735 for a solo two-manual harpsichord. It is one of Bach's more popular keyboard works and is in three movements (Allegro, Andante, Presto), about 16 minutes in length. Christian Birkness has arranged this music for three tubas (suggested 2 F tubas in F and 1 CC). The first part can also be played on euphonium, with only a few spots requiring a 4th valve. The arrangement is appropriate for advanced performers. -the publisher/cdp
