Abstract: For each section forming a music piece, music template information is supplied which includes at least information indicative of a pitch variation tendency in the section. A plurality of already-composed music pieces are preferably analyzed to store a plurality of pieces of such music template information so that any users can select from the stored pieces of music template information. For a music piece to be composed, the user enters information indicative of a tendency relating to the number of notes, such as syllable information of desired words or scat words, in each section of the music piece. On the basis of one of the pieces of music template information supplied and the user-entered information indicative of the number-of-notes tendency (syllable information), the length and pitch of notes in each section can be determined, which permits automatic generation of music piece data.

Abstract: A normal automatic accompaniment performance is executed in accordance with an accompaniment pattern read out from a pattern memory. When a special performance is designated such as an intro, fill-in or ending performance, a modification suitable for the special performance is applied to a accompaniment pattern read out from the memory, so that the special performance is inserted in accordance with the thus-modified accompaniment pattern. At that time, the pattern may be modified by desired modifier data describing a manner of modifying the pattern. The pattern modification can be diversified by setting an individual modification condition to each musical instrument part of the accompaniment pattern in correspondence to the designated modifier. A memory is provided for storing a number of modifier data, and a further arrangement is provided for freely editing the modifier data stored in the memory.

Abstract: A musical composition/arrangement assisting apparatus for assisting a composition/arrangement of a multi-part music receives performance information such as melody information, chord information, or the like, and detects candidate tones harmonizing with the performance information. The candidate tones are notes on an available scale determined by a tonality and a chord. Avoid notes are excluded in terms of a chord tone architecture from the candidate tones. Furthermore, tones parallel to melody tones or tones in a minor ninth relation to melody tones are excluded from the candidate tones. The candidate tones are informed a user of and presented to him or her. The user selects tones from the candidate tones to generate musical tone data of another part. The user can compose/arrangement other parts of a music from the candidate tones presented in consideration of musical harmony. Therefore, all the composed/arranged parts are musically harmonized with each other.

Abstract: In a pattern memory are stored plural performance patterns, each of which has one or more measures. Plural ones of the performance patterns are optionally selected and read out from the pattern memory, so as to make a music piece made up of time-series combinations of the selected performance patterns. The thus-made music piece is stored into a song memory. A suitable device such as a switch or a detector or a suitable process is employed to instruct to make a music piece in auftakt form. For this purpose, such a method may be employed, for instance, where it is detected that the melody part is in the form of an auftakt music piece, and in response to this detection, it is automatically instructed that the music piece made up of combinations of the performance patters should also be made in auftakt form.

Abstract: In an automatic arrangement apparatus, a melody of a part of an original musical tune is memorized in a melody memory (4), chord data of the original musical tune is memorized in a chord progression memory (5), and a rhythm pattern in a rhythm pattern memory (12) is selected in accordance with the style and composition of the original musical tune. At a timing of a note code of the selected rhythm pattern, a top-note, an additional tone, a bass part and a drum part are produced. The top-note is produced by referring to a top-note table stored in a top-note table memory (15) and corresponds with the chord. The additional tone is produced in accordance with the top-note and the chord on a basis of a voicing table stored in a voicing table memory (16). The top-note and additional tone can be selected at a continuous two-tone pair.

Abstract: An automatic arrangement apparatus for automatically producing performance data indicative of a predetermined performance part of a musical tune on a basis of an arrangement condition intended to be arranged. The arrangement apparatus includes a baeklng type table memory for memorizing rhythm backing and non-rhythm backing in compliance with a predetermined combination of a performance style, loudness of musical tones and a performance feeling or mood such as melodic or rhythmic feeling. Based on the arrangement condition applied from an external equipment such as an electronic musical instrument or an external recorder by operation of an Input device, either the rhythm backing or the non-rhythm backing is selected to produce a backing part at a timing of a rhythm pattern memorized in a rhythm pattern memory or at a timing of variation of chords memorized in a chord progression memory.

Abstract: An accompaniment apparatus has a first memory for memorizing a plurality of original accompaniment patterns corresponding to various accompaniment styles, each original accompaniment pattern being composed of a set of parallel part patterns. An editor is operated for designating different ones of the original accompaniment patterns and collecting therefrom a set of desired part patterns to define a free accompaniment pattern which is different than the original accompaniment patterns. A second memory memorizes designated and collected results by the editor for use in reproduction of the free accompaniment pattern. During the reproduction, a pattern length difference or a meter difference among the set of the collected parallel part patterns can be corrected to maintain a consistent progression of the automatic free accompaniment.

Abstract: In order to simulate sounds of an acoustic musical instrument such as a bowed stringed instrument, an electronic musical instrument employs a musical tone control apparatus which at least contains an operating device and a detecting circuit. Herein, when operating the operating device which can be operated in a two-dimensional area, the detecting circuit detects operation information corresponding to an operating position or an operating displacement of the operating device. Then, velocity information is generated based on the operation information. Thereafter, a musical tone is generated in response to a musical characteristic corresponding to the velocity information under a condition where the operating device is now operating. Preferably, the operating device is configured by a digitizer on which surface an electronic pen is moved two-dimensionally by the performer. Thus, it is possible to impart the varied performance expression to the musical tone to be generated.

Abstract: Melody and chord information of a music piece are supplied. On the basis of the chord information, one or more possible musical keys are nominated. Then, on the basis of the melody information, it is judged in a collating manner whether it is proper to determine any of the possible musical keys as a musical key of the music piece. For instance, the possible musical keys are nominated on the basis of detection of a dominant motion, since the dominant motion in a chord progression strongly suggests specific musical keys. For instance, of the nominated possible musical keys, those which do not contain all of the melody notes as their scale note are excluded, and a single musical key which contains all of the melody notes as its scale note is determined as the musical key of the music piece. With such arrangements, it is allowed to make a musical key determination which is very reasonable from a musical point of view.

Abstract: Melody note data and chord data are inputted to an automatic arrangement apparatus. When it is detected that a melody note is a nonharmonic note, the melody note is converted into a harmonic note, and an additional note (e.g., a countermelody note) is generated based on the converted harmonic note. An electronic musical instrument comprises such an automatic arrangement apparatus. Melody note data and chord data are inputted to the instrument according to a performance of a player. When it is detected that a melody note is a nonharmonic note, the melody note is converted into a harmonic note, an additional note is determined based on the converted harmonic note, and the additional note is produced as a tone in real time simultaneously with a performance tone.
