Abstract: An automatic composition apparatus is provided which enables the user to compose a piece of music while taking account of the overall structure of the melody of the piece of music as a whole. A CPU generates each of a plurality of layers of skeleton that constitutes a melody of a piece of music. The plurality of layers form a hierarchical structure formed preferably of a layer of an overall skeleton, a layer of an passage skeleton based on the overall skeleton, and a phrase skeleton based on the passage skeleton. The CPU generates each layer of skeleton except the highest layer of skeleton, based on at least one of the plurality of layers of skeleton that is higher than the each layer of skeleton.

Abstract: A data base includes a plurality of music data set specifying a plurality of sample musical pieces. Each sample musical piece is expressed and specified by either or both of melody characteristics or a melody itself with respect to the respective phrases on a phrase-by-phrase basis in a musical piece. The user inputs a melody fragment or melody characteristics for a particular phrase of a musical piece to be composed. The apparatus selects from the data base a musical piece including a phrase whose melody itself or melody characteristics is equal or similar to the melody fragment or melody characteristics as inputted by the user, and generates a melody fragment for the designated phrase to be included in a composed musical piece by utilizing the inputted melody fragment as it is or by generating a melody fragment based the melody or melody characteristics of the same phrase in the selected musical piece in the data base. Melody sections covering the remaining phrases are generated based on the melody data or the melody characteristics data of the remaining phrases included in the selected musical piece. The generated or utilized melody fragment for the particular phrase plus the generated melody sections for the remaining phrases in combination constitute an automatically composed musical piece product.

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. A still further arrangement is provided for dislaying the accompaniment pattern in the pre-modification state and the accompaniment pattern in the post-modification state for a visual comparison therebetween. There are also provided various methods to designated a desired modifier as well as various pattern modifying methods.

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: 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 translation: 提供音乐的旋律和和弦信息。 在和弦信息的基础上，提名一个或多个可能的音乐键。 然后，基于旋律信息，以对照方式判断是否适当地确定任何可能的音乐键作为乐曲的音乐键。 例如，可以根据主导运动的检测来指定可能的音乐键，因为和弦进行中的主要运动强烈地表示特定的音乐键。 例如，在所提名的可能的音乐键中，不排除所有旋律音符作为音符的音符，并且将包含所有旋律音符作为音符的单个音乐键确定为音符 音乐片。 通过这样的布置，可以从音乐的角度进行非常合理的音乐确定。

Abstract: A musical tone control apparatus controls a musical tone corresponding to a movement itself of an object and the like which is detected by a detector Such detector detects also a moving speed, a moving force, a moving angle or an intensity of given impulse of the object. In the case where the detector is mounted in the vicinity of a player's joint, the detector detects a revolving or bending angle of the player's joint. Hence, the musical tone can be controlled based on such angle of the player's joint. Thus, through this musical tone control apparatus, the player can generate a musical tone having, for example, a desirable tone pitch, a desirable volume and a desirable tone color based on the movement of the object or the player's joint.

Abstract: An envelope generator is provided with a count circuit the count value of which is varied through addition or subtraction or combination thereof, and a conversion circuit which operates to convert the count value into amplitude data, so as to generate an envelope having a shape corresponding to variations with time of the count value. According to one aspect of the invention, the count circuit is a circuit which carries out computation for exponentially varying the count value through polygonal line approximation, so as to form an envelope of exponential characteristic. According to another aspect of the invention, the conversion circuit is a memory which has stored amplitude data corresponding to count values in advance so as to convert count values in the last linear region of the envelope obtained by the polygonal line approximation into amplitude data in exponential relation and to convert count values contained in the remaining polygonal line regions into amplitude data in linear relation.
