Abstract:
1. A tone information processing apparatus comprising: a tone information acquisition section configured to acquire tone information indicative of a tone having a pitch element; a chord information acquisition section configured to acquire chord information designating a chord; a determination section configured to determine whether one tone indicated by the tone information, acquired by said tone information acquisition section, continuously varies from a first note pitch to a second note pitch, different from the first note pitch, during a sounding time period of the tone; and a pitch conversion section configured to convert a pitch of the acquired tone information so as to match the chord information acquired by said chord information acquisition section, wherein, when it is determined that the one tone indicated by the tone information continuously varies from the first note pitch to the second note pitch, said pitch conversion section converts the first note pitch and the second note pitch independently of each other so as to match the chord information.
