See and hear a sample of a classical arrangement for
melodeon:
J.S.Bach's Prelude from The Suite for Solo Cello No 1 in G
major both arranged for the C/F Castagnari Mory Diatonic
Accordion and performed by Tony Croft. Clearly the constraints of a
diatonic instrument have meant some compromises, but nevertheless I
hope you think the result is sufficiently pleasing!
