Abstract: A musical sound generation device including a blowing pressure sensor which detects a blowing pressure, a key switch which specifies a sound pitch of a musical sound, a first sound source which outputs a first signal corresponding to an exhalation sound, a second sound source which outputs a second signal corresponding to the musical sound having the sound pitch specified by the key switch, and a processor which starts output of the first signal by the first sound source on basis of an operation performed on the key switch, starts output of the second signal by the second sound source on basis of the blowing pressure, and controls a sound volume when the exhalation sound resulting from the first signal is emitted and a sound volume when the musical sound resulting from the second signal is emitted, on basis of the blowing pressure.

Abstract: Calculation is performed to provide a delay and attenuated oscillation to a blowing pressure detected by a blowing pressure sensor which detects blowing pressure, and a musical sound is generated based on the blowing pressure subjected to the calculation. As a result, for example, a blowing feeling of an electronic wind instrument can be made closer to a blowing feeling of a natural musical instrument.

Abstract: In the present invention, a CPU detects bar lines in a musical score image to divide at each bar line, and obtains the layout range of music notes in each measure obtained by the division. Subsequently, the CPU estimates the position of each music note in the obtained layout range by using music note data, and detects a matching value and a detected position of a music note at the estimated position as position candidates. Then, the CPU excludes a musically improper position candidate from among the detected position candidates, and determines the detected position of a position candidate having the highest matching coefficient among the remaining position candidates as the position of the music note.
