Yesterday we celebrated the 200th birthday of Franz Liszt. Countless concerts took place all around the globe, and I noticed contributions in radio broadcastings. His main instrument was the grand piano, but he also composed about a dozen pieces for the pipe organ. Organ players may remember »Praeludium und Fuge über B-A-C-H«, a piece quite difficult to play, which exposes the capabilities of the instrument in an excellent manner.
In case Jazz did not exist, I guess he was one of my preferred musicians :) .
