Musical stringed instrument

摘要

A keyboard musical stringed instrument having a plurality of vibratory strings; a plurality of projections individually related to the strings and rotated by a powered drive in individual orbits for engagement of their respective strings, a plurality of supports individually mounting the projections for engagements with their respective strings to a depth and with a rapidity which produces sounds resembling those of a bowed stringed musical instrument, and a plurality of key mechanisms individually related to the rings for selectively causing said engagement and for varying said engagement for the production of dynamic effects.
