Track 28-31 of the CD "cello - bass duets".
Benedetto Marcello: "Sonata in A minor"
In this sonata, too, the continuo part for the double bass has been reworked into an independent counterpart part, so that it becomes more interesting for the bassist, but equally more demanding, and the sonata takes on more of the character of a duet.
The sheet music is available here at PRObass Musikverlag under order number C 127.
violoncello: Paul-Gerhard Wiebecke
Double bass: Andreas Wiebecke-Gottstein
