Barenreiter Urtext edition: BA10544. Gioachino Rossini Andante for Violoncello & Double Bass. Composed in London near the end of 1824, the Duetto is one of the few chamber music works regularly performed today. It is a light & charming composition yet requires experienced performers. Bärenreiter’s critical edition is the only currently available publication which is based on Rossini’s autograph & not on the first edition.
