Self-playing Tuba

The self-playing mechanical tuba is a project that we have been dealing with for many years. The instrument plays like a real tuba, i.e. without a loudspeaker or similar.
Due to the relative accurate tone frequency generation, the instrument valves are not needed.
We built our first Tuba player figure according to the siren principle from Klaus Wogram around the year 2000.
