This is an arrangement of the Concerto for two violins in D minor by Bach. The two solo violins are accompanied only by cello. I have not edited the fingerings, so reading from the animated tablature will be difficult. A piece this complicated would be better learned from sheet music. If you would like me to edit the fingerings and bowings, please post in the forum under "Request for Content."
Sheet music can be found at IMSLP.org
Viola players can also play along, despite their part not being included in the audio.
