This book is intended for bass players who want to play some of J. S. Bach's beautiful music to improve their sight reading and technique. These two-part inventions were originally created for keyboard and have been adapted for two 4 string bass. In order to technically fit the range of the instrument some of the parts haven been transposed one octave up or down and some of the ornamentation and special notation has been simplified. On the online recording the right hand, part one, is on the right channel and the left hand, part two, on the left. Practice the parts by yourself before playing it along with the recording. Includes access to online audio.
