I do not want to make myself a nuisance, but I hope that the question I am gonna raise "Does the Preludio of J.S.Bach (whose BWV I am not able to recall) have an orchestral or organ version or was it converted from the composer's other work?" makes sense. The edition I have is EMI Nathan Milstein's Bach: Sonatas & Partitas. Thank u for ur attention! vonrud [log in to unmask]
