摘要： A plurality of display units are provided in corresponding relations to individual performance keys. A table stores, for each of a plurality of chords, information which defines plural groups of notes that are always available for the chord, temporarily available (e. g., a tension note) for the chord and unavailable for the chord. In response to designation of a chord according to a chord progression, the information is read out from the table and the display units are controlled according to the read-out information so as to dislay in different forms, depending on which one of the groups the performance keys corresponding to the display units correspond to. A performer can operate a desired key in consideration of different display forms. Thus, there is provided a music performance assisting system which is suited for use in executing an adlib performance with notes well conforming to a designated chord.

摘要： An automatic composition apparatus includes a processing unit. The processing unit performs a note pitch shift process, a matching-level calculating process and a melody generating process. The note pitch shift process performs pitch shift on pitches of individual note data items included in an input phrase. The matching-level calculating process calculates a matching level between a phrase including note data items subjected to the pitch shift and a designated chord progression data item, with reference to a plurality of note connection rules each of which defines a connection relation of consecutive note types, if the pitch shift is performed. The melody generating process generates a melody based on the phrase which includes the note data items subjected to the pitch shift and which is selected based on the calculated matching level.

摘要： A musical keyboard includes a plurality of white keys and black keys. As a number of keys are depressed simultaneously, a pattern of the depressed keys is judged as categorized in a number of predetermined patterns of depressed keys in view of the white keys and the black keys based on the input note data acquired from the depressed keys. A plurality of types of harmonization are predetermined, from among which a type of harmonization is determined. According to the determined type of harmonization, the input note data representing the notes of the depressed keys are adjusted so that inadequate notes included in the input notes are changed to adequate notes to constitute a chord as permitted by the type of harmonization in view of musical grammar. An unskilled player can play music incorporating improvisation which would need higher musical skill, as the inadvertently erroneous depression of the keys is rectified in the note data processing.

摘要： An electronic musical instrument provides an automatic key designating function capable of automatically designating a desirable key based on a chord and a rhythm kind which are respectively designated. The chord is designated by simultaneously depressing plural keyboard keys, while desirable one of plural rhythm kinds which are predetermined in advance is designated by the performer. In addition, a desirable mode can be determined based on the designated chord. Based on the mode, chord and rhythm kind, an automatic accompaniment can be performed. Further, this electronic musical instrument can also provide a chord detecting apparatus capable of automatically detecting a desirable chord based on plural notes or note names) designated by the performer. In such chord detection, an evasive note is automatically omitted from all notes designated by the performer, so that the desirable chord can be detected with accuracy.
