s1, detecting a note of a first bar beat point of the performed music;
s2, judging whether the chord is the first chord composition sound of the preset harmony proceeding mode according to the musical notes;
if so, go to step S3, otherwise, go to step S4.
S3, playing the first chord tone;
and S4, searching harmony sound proceeding modes containing the notes in the preset N harmony sound proceeding modes, switching the searched harmony sound proceeding modes when the harmony sound proceeding modes are searched, and playing.
Specifically, the system is provided with a template of classical song harmony behavior and harmony proceeding mode of a specified style, and searches in real time in a database according to the performance of a user until the most suitable chord is found and corresponding, and simultaneously determines the next chord to be pushed.
For example, the user performs a note C in the first beat of the first bar, where the repeated beat is the key beat point, and the system determines the note to sequentially determine whether the root, the third, and the fifth are matched, and first sequentially determines whether the note is the root, the third, or the fifth as in the flow shown in fig. 2.
According to the tone, the root note is judged. The system determines C chord and finds the first piece of matching harmony progression C-Am-F-G (as shown in fig. 3). And pushing the next chord Am according to the chord.
Further, the built-in harmony motion template is like a plurality of pipelines, the automatic chord matching is like a crawler, and as the beat point is moved (key beat point), the most suitable chord is continuously selected from the plurality of harmony templates to be provided for the user until the playing is finished. Firstly, when a user plays a sound C in the first beat of the first bar, the system finds a first matching harmony progression mode C-Am-F-G. And pushing the next chord Am according to the chord, but matching the playing sound with the harmony, and continuing according to the harmony proceeding mode. When the user performs sound D in the first beat of the third measure, the system switches to another harmony mode C-G-Dm-Am, where Dm is the matched harmony mode, and continues (as shown in FIG. 4).
Here, the beat point used by the program to make chord decision while the user is playing is the first half beat of beats 1 and 3 among beats 4/4 and 6/8; 3/4, 2/4 are the first beat and the first half beat.
In addition, the 50 classical tracks containing various styles are marked for chord progression, termination, and semi-termination, as well as music piece rules and exceptional tone global rules. The system automatically switches and selects the most suitable chord according to the data of the key beat point, and the subsequent harmony of the chord is pushed by default once the chord is selected. And the termination, semi-termination marking and music segment rule are used for using the flower arrangement and switching the variation during non-real-time creation.
Further, in an embodiment of the present invention, a music harmony determination method is further provided, and as shown in fig. 5, a flowchart of the music harmony determination method in the embodiment of the present invention is shown, where the method includes:
s51, determining a first chord progression according to the proportion of all recorded melody notes appearing in each measure;
s52, comparing the first chord progression with each chord in the chord matrix, and determining a second chord progression meeting the conditions;
s53, comparing the first chord with the second chord, and searching whether the different chords can be replaced according to the replacing chord table;
if so, go to step S54, otherwise, go to step S55.
S54, replacement writing;
s55, reserving the difference, and determining the optimized third chord progression;
s56, identifying the ending bar of the phrase and the music segment according to the ending chord noted in the chord matrix, and inserting the flower arrangement mark in the bar;
and S57, finding out corresponding measures according to the music piece rule, adding the flower arrangement marks and the variation marks, and completing harmony.
Specifically, in the embodiment of the present invention and the sound creation, the two modes of real-time creation and non-real-time creation are divided, and the real-time creation has been described in detail in the above embodiment, and the non-real-time creation can reconfigure a more suitable chord progression based on the ratio of chord interval and chord interval in the bar after the user creates and plays all data in real time, wherein the chord progression comprises various termination modes, and the judgment of the musical sentence and the musical interval, and the addition of necessary inserting flower variation and other controls.
Specifically, detecting a complete song played by a user, and dividing a musical section and a musical sentence according to a preset theoretical rule; detecting important beat points, accessory rhythm symbols, eight-minute long notes of the front sixteen and rear eight-rhythm types and an ensemble judgment chord; judging whether a harmony proceeding mode completely agrees exists according to the divided musical sections, the musical sentences, the important beat points, the accessory rhythm signs, the first sixteen and the last eight-rhythm type octave long notes and the repeat sound, and if so, playing a first chord sound; if not, searching the preset N harmony sound carrying modes including the musical notes and the harmony sound carrying modes, switching to the searched harmony sound carrying modes when the searching is completed, and playing.
For example, in the bar, the chord is determined by taking the number of times the chord root, the third note and the fifth note appear and the length of the duration as the main basis of chord determination, and when the chord duration appears more, the duration is longer. Non-real-time creation because the notes of the whole measure can be retrieved, the system can match the chord more accurately. And chord attributes can be more accurately judged.
The method provided by the invention can realize intelligent harmony creation, can enable a user to play music more easily and conveniently, and can enable the user to complete harmony creation with one hand.
In addition, by the method, real-time matching and sound can be guaranteed under certain sound matching theoretical basic support, and accuracy and convenience of sound creation are improved.
