New musical instruments #2: THE 24-STRING VIOLIN-CELLO by Joel Sattler
The materials available for manufacturing musical instruments are far in advance of what Stradivarius and the other technicians had to work with.
The 24-string cello has 24 strings of varying lengths attached to a cone that is attached at the bottom to the sounding board with a superstrong ball-and-socket device. The tuning keys are very small, and are tightened with an Allen wrench.
The cone can be turned while playing, and locked in place without any sound or interruption in playing.
The player turns the cone with a foot pedal.
The higher strings can be as short as a violin's, or even shorter.
This arrangement will allow the player a range utterly beyond beyond.
