Description

Technical Field

[0001] This invention relates to the field of music composition technology, and in particular to an intelligent chord generation method, system, and storage medium. Background Technology

[0002] Traditional music synthesizers have long faced the dual challenges of efficiency and flexibility in chord generation. Current technology requires users to manually combine notes or navigate through multi-level menus to select chord types, a cumbersome and time-consuming process. This complex input method severely limits the smoothness of composition, especially in real-time performance scenarios. Furthermore, traditional synthesizers often employ a standard piano key layout, which, while conforming to conventional playing habits, results in a large number of keys and a bulky design, taking up space and increasing portability, making them unsuitable for the miniaturized and mobile demands of modern music production.

[0003] More importantly, the parameter adjustments (such as timbre, effects, and rhythm) of traditional synthesizers are separated from the performance operation. Users need to interrupt the performance to adjust the menu or knobs, which greatly reduces the dynamic expressiveness. These shortcomings together lead to the problem that the existing technology has a high threshold for music creation and weak real-time interactivity, making it difficult to meet the needs of professional performers and amateur users for efficient and intuitive music production tools. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an intelligent chord generation method, which includes the following steps:

[0005] The physical encoder and chord type shortcut keys are used to obtain the user's selected scale, chord type and root note information;

[0006] Based on the user-defined scale, chord type, and root note information, the frequency of the waveform is modulated by a modulator, and the corresponding chord timbre characteristics are generated based on the principle of FM synthesizer.

[0007] The target chord is obtained by acquiring and correcting the chord timbre characteristics based on preset chord rules.

[0008] The system acquires and processes the target chords and bass parts in a coordinated manner based on the bass part parameters, and adjusts the arrangement rules of the chords and bass parts in real time to achieve synchronized performance of the chords and bass parts.

[0009] Optionally, the physical encoders include the Sound function encoder, Performance function encoder, FX function encoder, Key function encoder, Bass function encoder, LOOP function encoder, BPM function encoder, and Options function encoder.

[0011] Optionally, the LOOP function encoder recording clips are automatically associated with the tempo set by the BPM function encoder;

[0012] When the tempo set by the BPM encoder changes, the recorded clip automatically adapts to the new tempo while maintaining the same pitch.

[0013] Optionally, preset chord rules include chord construction rules and harmony principles from music theory.

[0014] Optionally, the chord timbre characteristics are obtained and corrected based on preset chord rules to obtain the target chord, including at least the following steps:

[0015] Get preset chord rules;

[0016] The chord timbre characteristics are compared with the preset chord rules to determine whether the chord timbre characteristics meet the harmony requirements of chord construction. If they do not meet the requirements, the chord timbre characteristics are automatically corrected.

[0017] The corrected notes are recombined to form the complete target chord, thus obtaining the target chord.

[0018] Optionally, the method further includes: dynamically adjusting the loudness and timbre characteristics of the target chord based on the pressure applied by the user to the keyboard keys.

[0019] Optionally, the keyboard keys use capacitive pressure sensors with preset graded force responses; a light press of a keyboard key triggers a single tone, while a harder press a keyboard key increases the overall volume.

[0020] Corresponding to the aforementioned intelligent chord generation method, the present invention provides an intelligent chord generation system, comprising:

[0021] The data acquisition module is used to acquire the user's selected scale, chord type, and root note information through the physical encoder and chord type shortcut keys;

[0022] The chord generation module is used to modulate the frequency of the waveform through a modulator based on the scale, chord type and root note information set by the user, and generate the corresponding chord timbre characteristics based on the principle of FM synthesizer;

[0039] Based on the user-defined scale, chord type, and root note information, the frequency of the waveform is modulated by a modulator, and the corresponding chord timbre characteristics are generated based on the principle of FM synthesizer.

[0051] This invention utilizes the correlation and automatic adaptation function between the LOOP and BPM encoders to automatically adapt the recorded segment without changing the pitch when the tempo changes. This greatly improves the flexibility and efficiency of music creation, avoids pitch errors caused by tempo adjustments, and makes it convenient for users to create and modify music at different tempos.

[0052] In this embodiment, the recorded segments of the LOOP function encoder are automatically associated with the tempo set by the BPM function encoder;

[0053] When the tempo set by the BPM encoder changes, the recorded clip automatically adapts to the new tempo while maintaining the same pitch.

[0058] Min (minor chord) chord structure: root note + minor third + perfect fifth.

[0059] The structure of a Maj (major key) chord is: root note + major third + perfect fifth.

[0060] Sus (suspended chord) chord structure:

[0061] Sus2: root note + major second + perfect fifth; Sus4: root note + perfect fourth + perfect fifth.

[0076] Preferably, the keyboard is a 12-key compact keyboard, including 7 white keys (CDEFGAB) and 5 black keys. The black keys are semitone keys used to raise or lower the pitch.
