Document Type and Number:
WIPO Patent Application WO/2019/026259
Kind Code:
A1
Abstract:
A performance evaluation device includes a determination unit and a detection unit. The determination unit determines whether or not the pitch of a performed sound generated from an instrument played by a user is different from the pitch of a sound that should be produced and the pitch belongs to the harmonic series of the pitch of the sound that should be produced. The detection unit detects a playing technique or playing error on the basis of a change in the pitch of the performed sound when the pitch of the performed sound is different from the pitch of the sound that should be produced and belongs to the harmonic series of the pitch. The change in the pitch of the performed sound may be the periodicity of the pitch of the performed sound.
