Publisher Desc.  J. S. Bach's monumental work transcribed for unaccompanied solo clarinet by John Gibson. In transcribing these works I have attempted to remain true to the composer's intentions while making the music as clarinet friendly as possible. For the Chromatic Fantasy, which was originally for keyboard, I chose to use the BWV 903a version that Bach wrote of the first 23 measures rather than the more often played BWV 903 since it was better suited for clarinet. This is music for advanced players!
