INSIDE THE

THEREMIN CELLO

 

Floyd Engels, builder of the modern theremin cello is shown above with

one of his recreations. Since no schematics existed for the instrument,

Mr. Engels was obliged to “backwards engineer” the construction

based on original vintage instruments in museums.

 

 

The theremin cello consists of two elements: the controller (that is the instrument you see

being held by Mr. Engels in the photo at the top of the page with its touch sensitive

fingerboard), and a cabinet which contains the sound producing electronics,

the amplifier, and the speaker.The photo above shows the inside

of an early original cabinet on the right, and Floyd Engels'

modern reproduction on the left.

the cabinet as a stool on which to sit when playing their instruments.
