Made in 1992, the microtonal
guitar (above, left) was Rubenstein's
first creation. Originally it had movable nylon frets but is now fretless.
The cellotar
(above, right) is one of a series of bowed, electric, stringed instruments
Paul made that include the viotar,
invisitar,
ubertar,
and alumitar.
The cellotar
has several lead weights at the bottom to allow for sliding notes without
lifting the instrument. The ubertar and alumitar are connected to a
swiveling stand and are played standing. The viotar,
invisitar
and cellotar
are played seated, like a middle-eastern rebab. |
