Inventions & Sinfonias by J. S. Bach

Bach wrote a set of fifteen two-part Inventions to serve two purposes.  They were intended to provide keyboard exercises of intermediate difficulty, and to demonstrate compositional techniques in counterpoint.  Bach also wrote fifteen three-part Sinfonias for the same purposes, with additional complexity.
