Bach’s Chromatic Fantasy and Fugue BWV 903 and 903a is one of his most fascinating works. It was apparently already greatly admired during his lifetime, for it survives in numerous copies which present some occasionally very different versions, especially in the Fantasy. Bach seems to have revised it several times; since there is no extant autograph, one of these divergent versions of the Fantasy has been reproduced in the Appendix of the Henle Urtext edition.
바흐의 무반주 환상곡과 푸가 BWV 903과 903a는 그의 가장 매혹적인 작품 중 하나입니다. 이 곡은 특히 환상곡에서 간혹 매우 다른 버전을 보여주는 수많은 사본으로 남아 있기 때문에 그의 생전에 이미 큰 존경을 받았던 것으로 보입니다.
