This Guy Is Building A New Instrument Called The Subcontrabassoon From His Own Original Design

Robert Bobo, a contrabassoon player, is designing and building an original “Subcontrabassoon” – a unique instrument of his own invention. Similar to the subcontrabass saxophone, the subcontrabass tuba and the Tubax, Bobo is creating his instrument to play at full octave range lower than his existing instrument.

In choosing the low range of the subcontrabassoon, I was driven by a desire not to make a quasi-subcontrabassoon, but a true subcontrabassoon capable of playing a full octave below the contrabassoon. This left B? or A as the two possible lowest notes. I chose A over B? mostly as a way of future-proofing the design

He is currently raising funds to through his website in order to truly realize his vision.
