It sounds a little sad….a little eerie, and beautiful all at the same time. Here is a performance of “Over The Rainbow” on a Theremin. The same type of instrument used for the Star Trek TV series theme.
This song was written by Harold Arlen for the 1939 MGM classic THE WIZARD OF OZ. It is widely believed to be the most loved and enduring popular song of the 20th century. It is played here on the 1929 RCA theremin that once belonged to the late Hollywood thereminist, Dr. Samuel Hoffman.
