Plate adjuster (versions)

FIELD: music.

SUBSTANCE: invention relates to percussion musical instruments, namely to plate-like rattle, and can be used in occupational orchestras, in people's instrumental and folklore ensembles. Plate adjuster includes plates made from wood, stanks-hemispherical rusks connected with cord. In first version, each plate with one side has constant thickness, and on other side of plate thickness is equal to t/n, where t is reference or design thickness of plate; n is coefficient of tempered halftone, wherein plates are fixed in upper part of thicker side. In second version, each plate with one side has constant thickness, and on other side of plate thickness is equal to t/n, where t is reference or design thickness of plate, n is coefficient of tempered halftone, wherein plates are fixed in upper part of thinned side. In third version, length of plates is calculated by formula L/n, where L is reference or design plate length, n is coefficient of tempered halftone, wherein plates are fixed in upper part of thicker side. In fourth version, length of plates is calculated by formula L/n, where L is reference or design plate length, n is coefficient of tempered halftone, wherein plates fixed in upper part of thinned side. In all versions coefficient of tempered halftone is equal to 1.05946.

EFFECT: expanded range of plate ratchet sounding till complete octave.
