An apparatus is to assist an unskilled player in playing a musical instrument (2, 9, 10) by detecting (11, 12, 13, 15, 301, 302, 51, 605, 815) the quantity of the player's manipulation against the instrument (2, 9, 10), modifying (14, 16, 214, 216, 305, 503, 505, 514, 816, 902) the detected manipulation quantity with reference to a recommended manipulation (Sb) to a degree according to a given assistance coefficient (r, r2), and actuating (17, 18, 19, 20, 21, 301, 302, 303, 304, 305, 306, 307, 308, 309, 310, 401, 402, 403, 404, 405, 406, 517, 603, 604) the instrument (2, 9, 10) with the modified manipulation quantity. For a brass instrument (2), the apparatus comprises an embouchure sensor (11) and a breath pressure sensor (12) to detect the embouchure and the breath pressure of the player as he/she plays the brass instrument (2). The detected embouchure and breath pressure are then modified with reference to a recommended embouchure and breath pressure weighted by a given assistance coefficient. The apparatus actuates the brass instrument based on the modified embouchure and breath pressure.

Musical sound data derived from the musical instrument (1) is outputted via a capture filter (21), and effector filter (22), a flow-rate monitoring filter (23), and a renderer filter (24) to a speaker (3). The flow-rate monitoring filter (23) counts a buffer number "Cr" under rendering process among a plurality of buffers 24a employed in the renderer filter (24), and then, feeds back this count result to the capture filter (21). The capture filter (21) deletes, or inserts data based upon this feedback information by way of an interpolation.

Tone synthesis apparatus synthesizes a tone of a wind instrument generated in response to vibration of a reed contacting a lip during a performance of the wind instrument. First arithmetic operation section solves a motion equation (A1) representative of behavior of the reed in an equilibrium state with external force acting on the lip and a second motion equation (A2) representative of behavior of the lip in the equilibrium state, to thereby calculate displacement yb(x), y0(x) of the lip and reed in the equilibrium state. Second arithmetic operation section solves a motion equation of coupled vibration of the lip and reed with calculation results of the first arithmetic operation section used as initial values of the displacement yb(x), y0(x) of the lip and reed, to thereby calculate the displacement y(x, t) of the reed. Tone is synthesized on the basis of the displacement y(x, t) calculated by the second arithmetic operation section.
摘要:
Tone color data are stored in a tone generator storage region of a RAM (4). The tone generator data storage region (4) is searched upon occurrence of performance information indicative of a change of tone color, to determine whether tone color data selected by the change of tone color are stored in the tone generator data storage region (4), and musical tone generation is controlled such that when a result of the searching indicates that the tone color data selected by the change of tone color are stored in the tone generator data storage region (4), a musical tone is generated based on the tone color data, and, when the tone color data selected by the change of tone color are not stored in the tone generator data storage region (4), the tone color data are read out from a storage medium (100) storing the selected tone color data, and transferred to and stored in the tone generator data storage region (4), while generating a musical tone based on other tone color data similar to the selected tone color data.

摘要:
A mute detachably attached to a brass instrument includes a fixed part and a plurality of branch pipes, each including a main pipe and an auxiliary pipe. The branch pipes are unified together and inserted into a bell pipe of a brass instrument. The fixed part is attached to the tapered portion of a bell pipe and interposed between the interior of the bell pipe and the exterior of the main pipe. The branch pipe is designed such that the auxiliary pipe is connected to the main pipe at an interconnect part, at which an air flow propagating through the main pipe is partly branched into the auxiliary pipe.
摘要:
A wind instrument is constituted of a mouthpiece and a pipe structure including tapered/straight pipes. The pipe structure is constituted of a blow member and a branch pipe. The branch pipe is branched into a main pipe and an auxiliary pipe, which are straight pipes having openings and connected together in a branch shape. The blow member is connected to a branch point of the branch pipe. The branch pipe simulates resonance characteristic of a tapered pipe having a predetermined length, a predetermined distance between the upper base and the vertex, and a predetermined sectional area of the upper base commensurate with the sectional area of the main pipe.
