Virtual Sheet Music® Premium High-Quality digital sheet music for cello, bWV 1007-1012, revised edition March 2019. Brilliant quality print, so crisp and clear. A delight to have an edition that is so true to the original bowing. A jewel in the music library and a hugely rewarding challenge in every piece. These pieces arnt that hard they just take practice and they will stick with you because they are really fun! I am 15, and this is and excellent piece! I highly recomend it!
