Clarinet Solo - Level 5 - Digital Download SKU: A0.874586 Composed by Johann Sebastian Bach. Arranged by John Romano. Baroque. Individual part. 7 pages. John Romano #4625501. Published by John Romano (A0.874586). The Chromatic Fantasia (BWV 903) is a unique example of Bach's tonal experimentation that has been regarded as a masterpiece since the time of it's composition. A transcription for solo clarinet was done by Gustave Lengenus in the 1940s but has been permanently out of print for years. This current arrangement resurrects the monumental piece from oblivion and returns it the repertoire of the clarinet. The key has been kept in the original d minor to match the bass clarinet version and to work with the Chromatic Fugue for clarinet trio (sold separately).
