PURPOSE:To eliminate the need for processing, etc., for a passing tone and actualize portament which is free from a feeling of auditory disorder by an easy method by performing portament processing which allows a leap of high pitch halfway. CONSTITUTION:The electronic musical instrument 10 consists of a sound generation indicating means 11, a high pitch indicating means 12, a timbre specifying means 13, a sound source 14, and a portament control part 15. When the high pitch of a musical sound PN is indicated by the portament indicating means halfway in the generation of the musical sound PN, the musical sound waveform used to generate the musical sound PP is used and the pitch varies sequentially to the high pitch side of the musical sound PN so that 3rd high pitch is reached at a specific point t0 of time; and discontinuance of the pitch is allowed at the point t0 of time and the musical sound waveform used to generate the musical sound PN is used to generate a musical sound of 4th high pitch which shifts from the pitch of the musical sound PN to the high pitch side of the musical sound PP, and the pitch varies sequentially to the high pitch of the musical sound PN after the point t0 of time. |
