Claims (1)

[Claims for Utility Model Registration] 1. A plurality of wave body generating means disposed at intervals, and a wave body disposed corresponding to each of the plurality of wave body generating means and output from the wave body generating means. a plurality of wave body receiving means capable of receiving waves reflected by a reflecting object; a distance measuring means for measuring the distance between the reflecting object and the wave body receiving means; and a distance measuring means corresponding to the measurement result of the distance measuring means. Select one of the following: a scale consisting of pitches with neither a 彡 sign nor a flat sign, a scale including a pitch with a 彡 sign, or a scale including a pitch with a flat sign, and accept a wave body. a musical tone signal generating means for generating a musical tone signal of a predetermined pitch in any of the above-mentioned scales selected in correspondence with the wave body receiving means; and a sound generating means comprising a musical tone signal generating means. 2. A plurality of wave body generation means arranged at intervals, and a wave body arranged so as to correspond to each of the plurality of wave body generation means and outputted from the wave body generation means and reflected by a reflecting object. a plurality of wave body receiving means that can be received; a distance measuring means that measures the distance between the reflecting object and the wave body receiving means; and a distance measuring means that corresponds to a white key of a key instrument corresponding to the measurement result of the distance measuring means. Select either a scale consisting only of pitches or a scale consisting only of pitches corresponding to the black keys of a keyed instrument, and select one of the scales selected corresponding to the wave body receiving means that received the wave body. A musical tone control device comprising musical tone signal generating means for generating a musical tone signal of a predetermined pitch. 3. A plurality of wave body generation means arranged at intervals, and a wave body arranged so as to correspond to each of the plurality of wave body generation means and outputted from the wave body generation means and reflected by a reflecting object. A musical tone signal of a specific pitch corresponding to a plurality of wave body receiving means and a wave body outputted from each wave body generating means is received by the corresponding wave body receiving means. the wave body generating means and the wave body receiving means generate a musical tone signal of each pitch corresponding to a white key of the key instrument. A musical tone control device capable of controlling each pitch corresponding to a black key within a wider range than the wave body generating means and wave body receiving means.
