4 songs without words Op. 19 1 and 2 and Op. 30 1 and 4  in a version for double bass and piano by Karl-Hans Bonzelett. He was a  student of Prof. Rolf Heister who writes about the pieces: "I have  studied the  Mendelssohn's arrangements (songs without words) with joy.  The works "lie" to the instrument well and contribute certainly to the  musical development of the players. One can bring the pieces well to the  blade because the play positions are normal. Thousand thanks for the  splendid work!"
