Abstract:
A wide band multi-mode adjustable-tonality end-pin holder with field adjustable tonality for enhancing and optimizing the tonal balance and sonic quality of instruments with end-pins, utilizing a plurality of wood species including those not normally associated with orchestral instruments, comprising:(a) a solid, flat, triangular base provided with compliant feet serving not only to anchor the instrument and decouple it from a stage floor, but also to create a musically relevant resonance, surface and edge contours for increasing the proportion of higher frequency resonances, and a horizontal discontinuity at one end of said base fitted with an adjustable threaded fastener for high-frequency tonality adjustment;(b) a trapezoidal end-pin retainer with through-opening, edge contours, and adjustable threaded fasteners including one extra long fastener for converting the interface between said base and the stage floor from an interface that decouples and attenuates the transfer of vibrations to an interface that couples and promotes said vibrations, and one or more trapezoidal gouge plates, and compliant washers between said end-pin retainer and the upper gouge plate to create a variable bass resonance/tonality the frequency of which is adjustable with said fasteners;(c) a plurality of bar resonators with varied lengths, shapes, and materials, and adjustable threaded fasteners that allow said resonators to resonate freely or be dampened against the base by tightening said fastener.
