摘要： A chord performance training system is realized on a personal computer having a display and a keyboard in accordance with music application software. The display provides a user with three types of windows on a screen, namely a main window for displaying chord progression, a select window for displaying a list of genre names for selection and a score window for displaying a score. On the select window, the user selects a specific single genre name to activate model performance information containing chord parts, a percussion part, a chord text and a song text, so that the main window shows chord progression representing chord names and generation timings of chords which are to be sequentially played by the user. Multiple sets of model performance information are provided to suit to different levels, namely a beginners' level and an expert level, which are set to the user in playing chord performance on the keyboard. Incidentally, the select window shows histograms each of which shows a score being marked for user's chord performance out of ten grades with respect to each of the genre names, while the score window shows a highest point of score being marked for the user in the past out of a hundred. The user's chord performance is evaluated in comparison with the model performance information suited to a desired level in consideration of a degree of match being detected between a key-depression pattern and a chord pattern within an allowable time range (e.g., 300 msec).

摘要： For both an automatic chord correction and an automatic composition, it is required to correct a part of a series of given chords in order to have a musically natural connection between adjacent chords. A series of chords “a”, “b”, “c”, “d”, “e”, “f” (each letter means one kind of chords) for a music is selected by a user. If two chords “c” and “d” among the series of chords “a”, “b”, “c”, “d”, “e”, “f” are changed into different ones, according to the user's preference or to make them more appropriate to the motif melody, the chord “b” adjacent to the changed “c” is automatically corrected into “b*” so that both chord connections from “a” to “b*” and from “b*” to the changed “c” can be more musically natural. Similarly, the chord “e” adjacent to the changed “d” is automatically corrected into “e*” so that both chord connections from the changed “d” to “e*” and from “e*” to “f” can be more musically natural.

摘要： A rhythm pattern is provided to be subjected to forward syncopation processing. The time position of an un-syncopated note in the rhythm pattern is shifted forward to render advanced beating of the note to make a forward-syncopated rhythm pattern. The notes in the modified rhythm pattern are given respective note pitches to establish a melody, wherein the skeleton notes in the rhythm pattern are given skeleton pitches, and the non-skeleton notes in the rhythm pattern are given non-skeleton pitches. The advanced beating of a note makes a skeleton note which plays an important role in syncopation.

摘要： A musical instrument and a method for automatically playing a musical accompaniment by guiding smoother and easier chord patterns to play. The present invention indicates chord forms which realize smoothest fingering after analyzing a chord following the present chord to determine whether the present chord should employ a root position or an inverted position for the smoothest fingering. Another feature of the present invention is to indicate chord forms which are selected to realize less movement of the player's hand after analyzing the former chord to determine a chord position (root position or inverted position) of the present chord which is the closest to the former position.

摘要： In accordance with the musical performance by the player, a musical keyboard and an associated processor generate note command signals indicative of note pitches of the tones to be produced in response to which keys are depressed and intensity signals indicative of intensities of the tones to be produced in response to how strong the keys are depressed. A tone generator generates tone signals having pitches and intensities as determined by the note command signals and the intensity signals. A judger judges whether the intensity signals are greater than a predetermined threshold value. When the judgment is affirmative, an additive note designator generates additive note designating signals indicative of note pitches of the tones to be produced in addition to the tones produced as commanded by the depressed key, in which each additive note pitch has a harmonious relation to the corresponding key-commanded note pitch. The tone generator further generates additive tone signals having pitches designated by the additive note designating signals. An alternative detector judges whether the depressed key is a chord constituent note of the chord for the musical performance at that moment.
摘要翻译：根据播放器的音乐表演，音乐键盘和相关联的处理器产生指示要响应于哪个键被产生的要产生的音调的音高音调的音符命令信号，以及指示要产生的音调的强度的强度信号响应键的压力有多大。音调发生器产生具有由音符命令信号和强度信号确定的间距和强度的音调信号。判断器判断强度信号是否大于预定阈值。当判断是肯定的时候，附加音符指示符除了产生的音调之外，还产生指示要产生的音调的音调音调的附加音符指示信号，其中每个添加音符音调具有与该音调相关的和谐关系相应的按键指令音调。音调发生器还产生具有由加法音符指定信号指定的音高的附加色调信号。一个替代的检测器判断按下的键是否是用于此时的音乐表演的和弦的和弦构成音符。

摘要： A musical instrument and a method of operating it. An instrument and method which retunes and adjusts volumes in response to the chord being sustained and the way that chord is voiced. The instrument is capable of producing tones, the intervals between which are equal tempered intervals of a twelve note octave, and tones, the intervals between at least some of which are determined by identifying at least selected ones of the notes the instrument is being commanded to produce. The method includes identifying the at least selected ones of the notes the instrument is being commanded to produce, providing a map for mapping the identified notes to a chord type, identifying a note in that chord type, and substituting a frequency closer to a harmonic of the identified note for the frequency of at least one harmonic of at least one other note the instrument is being commanded to produce.

摘要： In accordance with a rhythm of a main melody, a auxiliary-melody or counter-melody creating rhythm pattern is supplied which indicates timing of respective hit points of a plurality of tones in the auxiliary or counter melody. Predetermined important hit points and unimportant hit points in the supplied rhythm pattern are discriminated from each other. Any one of component notes of chords, specified by a previously-supplied chord progression, is allocated to each of the thus-discriminated important hit points, while any one of scale notes, corresponding to previously-supplied scale information, is allocated to each of the unimportant hit points. Thus, an auxiliary or counter melody is created on the basis of the notes allocated to the individual hit pints.

摘要： A method and apparatus for performing music on an electronic instrument in which individual chord progression chords can be triggered in real-time, while various individual notes of the chord, and/or possible scale notes and non-scale notes to play along with the chord, can be generated from separate fixed locations on the instrument, and in different octaves. The method of performance involves the designation of a chord progression section on the instrument, then assigning chords or individual chord notes to this chord progression section according to the defined customary scale or customary scale equivalent of a song key. Further, as each chord is played in the chord progression section, various individual notes of the currently triggered chords can be generated from separate fixed chord locations on the instrument, and in different octaves. Fundamental and alternate notes of each chord can be generated from separate fixed chord locations on the instrument for composing purposes, and in different octaves. Possible scale notes and/or non-scale notes to play along with the currently triggered chord, can also be generated from separate fixed locations on the instrument, and in different octaves. All performance data can be stored in memory or on a storage device, and can later be retrieved and performed by a user from one or more fixed locations on the instrument. The performance data may also be performed using a variable number of input controllers. Further, multiple instruments of the present invention may be used together to allow interaction among multiple users during performance, with no knowledge of music theory required.
