摘要： An arrangement support apparatus for producing automatic accompaniment performance data for a musical tune. The musical tune is divided into a plurality of sections, and an arrangement condition is input for each of the sections. Utilizing the arrangement conditions, the apparatus selects an accompaniment pattern corresponding to at least one accompaniment performance part for each of the sections of the musical tune. The apparatus then produces automatic accompaniment performance data for the musical tune utilizing the selected accompaniment patterns.

摘要： The present invention is directed to an apparatus and method for automating accompaniment to an ensemble's performance. The apparatus is comprised of a plurality of input devices with each input device producing an input signal containing information related to an ensemble's performance. A plurality of tracking devices is provided, with each tracking device being responsive to one of the input signals. Each tracking device produces a position signal indicative of a score position when a match is found between the input signal and the score and a tempo estimate. A first voting device is responsive to each of the position signals for weighting each of the position signals. The weighting may be based on the frequency with which it changes and the proximity of its score position to each of the other score positions represented by each of the other position signals. The same weighting factors are then applied to the tempo estimate associated with that position signal. After the position signals and tempo estimates have been weighted, the voter device calculates a final ensemble score position signal in response to the weighted position signals and a final ensemble tempo based on the weighted tempo estimates. A scheduler is responsive to the final score position and final ensemble tempo for outputting an accompaniment corresponding thereto.

摘要： While automatic accompaniment for chord, bass, rhythm etc. is performed in accordance with a normal pattern, the normal pattern is changed over to a fill-in pattern in response to actuation of a fill-in switch. Then, automatic accompaniment based on the fill-in pattern is repetitively performed as long as the fill-in switch is actuated. When the end of the fill-in pattern is detected, repeat control of the fill-in pattern causes the fill-in pattern to be repeated from a predetermined intermediate point (for example, the head of a predetermined intermediate measure of the fill-in pattern). As the result, the introductory portion of the fill-in pattern is performed only once so that it is never performed during repetition of the fill-in pattern. This can avoid undesirable musical unnaturalness due to repetition of the introductory portion.

摘要： A melody segmentation module segments a given melody into a plurality of phrases. A phrase tonality analyzer determines a key of each phrase to provide a correct succession of keys of the melody. With this arrangement, the music apparatus can detect, from the melody, a modulation (change of key). A chord progression database is searched to assign an appropriate chord pattern to each phrase. Thus, the melody is harmonized with a natural and real chord progression. A style analyzer tests a melody phrase for a preselected music style and labels it with style-matched if it meets the preselected music style. A chord pattern characteristic of the preselected music style is selected from a chord progression database of the same music style to harmonize the style-matched phrase. Thus, the melody agrees with the harmonizing chord progression in terms of music style.

摘要： When a switching operation from a normal pattern to a special pattern is instructed while an automatic accompaniment operation is being executed using normal pattern data, the pattern to be read out is switched from the normal pattern to the special pattern in accordance with the instruction. In this case, when it is instructed to switch the pattern within the instructed bar, only a rhythm part of a plurality of parts is switched from the normal pattern to the special pattern. When it is instructed to switch the pattern at the beginning of the next bar, other parts in addition to the rhythm part are switched from the normal patterns to the special patterns.

摘要： A method and an apparatus for controlling scale practice of an electronic musical instrument. The apparatus includes a function select switching section for selecting a desired one of various functions according to a user's selection. The function select switching section is provided with a scale practice switch, a scale select switch, a minor switch, an increment switch, a decrement switch, a random switch and a note hearing test switch. If the scale practice switch and the scale select switch are selected, sequentially varied scales are displayed on a display unit and one thereof is then selected by the user. The selected scale is displayed on the display unit. A minor or major of the selected scale is set if the minor switch is selected. Tunes with sequentially incremented or decremented notes and randomly varied notes are selected if the increment or decrement switch and the random switch are selected. The selected tunes are displayed on the display unit according to the selected scale. Only when the first one of the notes of the presently displayed tune and a note pushed by the user are the same, the operation proceeds to the next note. A random note is given to the user if the note hearing test switch is selected. The operation proceeds to the next note only when the random note and a note pushed by the user are the same.

摘要： A CPU extracts a specified number of tones, in order of lower pitch from among notes of pressed keys and then determines a chord based on the specified tones so that a musical relationship can be established between the tones corresponding to the depressed keys and the generated chord, thus eliminating incongruity in the performance. In addition, since the chord detection is made based on the specified number of tones, there is no need to play all the constituent notes of the chord. Moreover, by storing chord pattern abbreviations in chord table memory, chords are detected in the manner that of frequently occurring abbreviated chord patterns are prioritized over infrequently occurring chord patterns.

摘要翻译： CPU从按下的键的音符中以较低音调的顺序提取指定数量的音调，然后基于指定的音调确定和弦，使得可以在对应于按下的键和产生的和弦之间的音调之间建立音乐关系 ，从而消除了性能的不协调。 此外，由于基于指定数量的音调进行和弦检测，因此不需要播放和弦的所有构成音符。 此外，通过将和弦图形缩写存储在和弦表存储器中，以频繁出现的缩写和弦图案在不经常出现的和弦图案上被优先排列的方式来检测和弦。
