This is the sheet music for electric bass of the left hand part of Bach's "The Well-Tempered Clavier, Book 1, No. 2 in C minor".
It is also famous for being played on Jeff Berlin's album PUMP IT.
This piece not only has a cool sound, but I also think it's a great practice piece for bassists. It's perfect for training how to assign four fingers of your left hand to four frets, and for training how to alternate two fingers of your right hand (two-finger technique) to move accurately and improve your stamina.
For reference, I've also included information on which fingers of your left hand are best to use to press the notes.
I think this will be useful for everyone, from beginners to advanced players, so please feel free to use this TAB.
