A board for a stringed instrument which forms a front plate or a back plate of a stringed instrument, includes: a veneer that includes a concave portion for partially reducing the thickness of the veneer, in which the veneer is curved to be convex toward one surface side. In this board for a stringed instrument, fiber of the veneer may extend along the curved shape of the veneer.

An electronic musical instrument includes a tuning device, a keyboard, a tone generator, a microphone, a measurement unit, and a display attached to the backside of the housing. The tone generator generates a plurality of reference tones in response to the operation of the keyboard, while the microphone receives a plurality of musical tones, which are generated by at least one musical instrument subjected to tuning. Different tone colors can be applied to the reference tones. The measurement unit measures a plurality of pitch differences between the reference tones and the musical tones subjected to tuning, so that the display displays the pitch differences in comparison with each other.

Electronic musical instrument having tuning device

There is provided a musical tone control apparatus that enables a user to easily play a musical instrument without spoiling the user's feeling that he is actually playing a musical instrument. A storage device stores musical piece data containing interval data indicative of intervals of musical tones constituting a musical piece. A motion of an operator is detected. A controller provides control so as to instruct a musical tone output device capable of outputting musical tones to adopt the intervals as one of characteristic amounts relating to musical tones to be output from the musical tone output device, according to the interval data, and instruct the musical tone output device to adopt at least one of the characteristic amounts other than the intervals according to the detected motion of the operator.

Musical tone control apparatus and method

A stereo sounding method which can provide realistic sounds such as stereo sounds for a large number of listeners while reducing the number of speakers. A stereo sounding system is comprised of a plurality of stereo sound sources, and a plurality of speakers. A smaller number of speakers than twice the number of the plurality of stereo sound sources are arranged, and an R-channel output from at least one stereo sound source among the plurality of stereo sound sources and an L-channel output from a stereo sound source other than the at least one stereo sound source are mixed, and the mixing result is output to at least one of the arranged speakers.

A tuner apparatuscauses a user to designate a musical instrument that is to be tuned and a reference pitch that is a standard upon tuning, by a process at a setting portion. A pitch detecting portiondetects a pitch of a performed note inputted via a microphoneand input portion. A target note specifying portiondefines a note name, which is positioned nearest to the performed note in a predetermined temperament (e.g., 12-note equal temperament), as a target note based upon the detected pitch of the performed note and the inputted reference pitch. Then, a calculating portioncalculates a difference between the pitch of the performed note and the pitch of the target note, and a display control portioncauses the display deviceto display the calculated difference. Further, the display control portionconverts the target note into a note name written in a score relating to the musical instrument to be tuned by using a transposition parameter relating to the musical instrument to be tuned that is stored in the storage portionand set by the setting portion, and causes the display deviceto display a staff in which a note corresponding to the note name written in a score is written.

Tuner apparatus for aiding a tuning of musical instrument

There is provided a musical composition data editing apparatus which enables the generation of musical composition data using which a user can cause his/her own musical image to be reflected to a high degree in a musical composition performance through simple operations, whereby a wide variety of users from beginners having no knowledge of musical composition data such as MIDI data to experts who want to arrange musical compositions in their own manner can be satisfied. A standard musical composition data generating sectionof a contents server CS refers to musical composition reproduction control codes for controlling reproduction of a musical composition contained in source musical composition data, to determine whether or not a musical image in the musical composition reproduction changes. When it is determined that the musical image in the musical composition reproduction changes, rewriting of the musical composition reproduction control codes is carried out such that a musical composition reproduction state becomes constant.

In an instrument performance learning apparatus, a storage section stores model performance waveform data representing a time series of individual performance sounds of a model performance. An input section inputs real performance waveform data representing a time series of individual performance sounds of a real performance. A pitch graph display control section detects each pitch of each individual performance sound from the stored model performance waveform data and from the inputted real performance waveform data, and displays a pitch graph representing transitions of the detected pitches. An amplitude envelope graph display control section detects each amplitude level of each individual performance sound from the model performance waveform data and from the real performance waveform data, and displays an amplitude envelope graph representing transitions of the detected amplitude levels, such that the amplitude envelope graph has a time axis common to that of the pitch graph while the amplitude envelope graph is located in an area of the display device which does not overlap with another area of the display device where the pitch graph is located.

There is provided a tone generating apparatus and method that enables recording and reproduction of performance made by a performer without requiring any complicated operations. Musical tones generated from a musical instrument are detected, and tone data is stored in a storage device, and the tone data stored in the storage device is reproduced and at least one tone corresponding to the tone data is egenrated when no next musical tone is detected within a predetermined period of time after a musical tone is detected.

Tone generating apparatus, tone generating method, and program for implementing the method

There is provided a musical tone generation control system that, even if the player moves, enables him/her to listen to good musical tones at a location to which the player has moved without the necessity of making adjustments by himself/herself. Information on a position of a listener is detected. A plurality of speakers are provided for sounding musical tones corresponding to a musical tone signal supplied from said tone generator. The volume of musical tones to be sounded from the plurality of speakers according to the detected position.

Musical tone generation control system, musical tone generation control method, and program for implementing the method

There is provided a musical tone generating apparatus which enables beginners inexperienced in musical performance and like players to play a musical instrument such as an electronic harp without practicing repeatedly. The musical instrument has a plurality of operating elements such as strings to which a plurality of musical tones are assigned, respectively. Musical tones are generated in response to operations of the operating elements. Ones of the musical tones, assigned to ones of said operating elements which are not to be operated are muted.
