Self-playing Tuba / Self-playing Sousaphone / Self-playing Alphorn

The self-playing Tuba is a project, with which we are concerned several years. The instrument plays like a real tuba. There is no speaker in it.
We built our first Tuba player according to the siren principle from Klaus Wogram around the year 2000.
