Abstract: For each sound of a model performance, performance information designating a sound generation timing and sound are supplied, and for each of a plurality of phrases into which the model performance is divided, intensity information indicative of an intensity of sound for the phrase is supplied. In accordance with a progression of a performance time and for each phrase of the model performance, the intensity information is acquired ahead of a start timing when a performance of the phrase is to be started, and the intensity of sound common to sounds in the phrase is presented based on the acquired intensity information. The intensity of the sound is presented in a visual or audible manner. In this way, a human player can know, through a visual display and/or an audible sound, an intensity of a key depression operation for each phrase of the model performance before starting the phrase. As a result, the human player can practice the performance while being aware of the intensity of sound for each phrase.

In accordance with a progression of a performance time and for each sound of the model performance, the intensity information is acquired ahead of the sound generation timing, and the intensity of the sound is presented based on the acquired intensity information. The intensity of the sound is presented in a visual or audible manner. In this way, a human player who receives sound-intensity-related performance operation training can know, through a visual display and/or an audible sound, an intensity of each sound of the model performance before the sound generation timing of the sound. As a result, the human player can practice the performance while being aware of the intensity of each sound of the model performance.

Abstract: An apparatus for practicing playing music on a musical instrument provides a stepped lesson comprised of a series of lesson steps about a subject music piece, each step providing practicing materials for a user to master for playing the subject music piece. The lesson steps are given to the user step by step. The apparatus stores a music-playing data set of a subject music piece for a reference and a music-playing data sets of the stepped lesson, and comprises a music-playing input device for the user to input music-playing manipulations. The apparatus judges, at each of the lesson steps, the achievements of the user in comparison with the reference music-playing data. The apparatus keeps a pass/fail score table for recording pass/fail judgments about the achievements of the user with respect to the respective lesson steps. The user can practice lesson steps selectively with reference to the pass/fail score table about his/her achievements.

Abstract: Chord to be performed is presented to a user. Chord is detected based on one or more notes performed by the user. When it is not detected that a chord has been duly established, one of the notes performed by the user is detected as a root note of a chord. Comparison is made between the chord presented to the user and the detected chord to make a determination as to whether at least the root note of the detected chord matches the root note of the presented chord. The user is informed of a result of the determination. Thus, not only when the user has accurately executed performance operation for all component notes of the presented chord but also when the user has executed performance operation for only the root note of the presented chord, a chord performance evaluation is made, determining that the user has accurately performed.
