While Dotzauer is most known for his works for cello, the piano was his first instrument and he always treated it with the greatest care, from the abundance in counterpoint reminiscent of Bach to exquisitely thought chamber music parts.

Here’s a performance of the first of these six waltzes for you to enjoy:
