Description
G10C covers keyboard-operated stringed instruments where sound is produced through mechanical action on tensioned strings. This classification encompasses pianos (grand and upright), harpsichords, spinets, virginals, and related instruments featuring one or more keyboards with mechanisms that strike, pluck, or otherwise excite strings. The subclass includes innovations in action mechanisms, string arrangements, resonance design, damping systems, and structural elements specific to these instruments. Adjacent mechanical music instruments without keyboards (such as guitars or violins) are classified elsewhere in G10D.
