The Clavioline is an early electronic keyboard instrument, similar to my Hammond Solovox. Both of them are monophonic (single voiced) and tube powered, consisting of a keyboard and an amplifier. The first photo shows my Clavioline after restoration. In the second photo, my son, Peter, is seated at the keyboard. Click the musical icon to hear him

Furthermore, since a patent is drafted to protect ideas and principles in the broadest possible fashion, this one doesn`t literally describe the Clavioline as it was commercially realized.
