The present application relates to the technical field of music-assisted creation, and discloses a music keyboard interaction method and its device, equipment, and medium, including: displaying a creation interface, the creation interface includes a composition area and a music keyboard, the composition area includes a plurality of note grids divided according to the dimensions of rhythm and scale; determining the notes in the key corresponding to the key signature according to the pre-selected key signature, establishing a sequential mapping relationship between each note in the key and each standard key in the music keyboard, so that each standard key corresponds to each note in the key one by one, and the note in the key with the lowest scale is mapped to the standard key corresponding to the starting note; responding to the note grid selection event in the composition area, playing the note in the key corresponding to the note grid, playing the animation effect of the standard key corresponding to the note in the key, and adding the time information of the rhythm dimension corresponding to the note grid associated with the note in the key to the melody construction information. The present application constructs a standardized music keyboard, which can enrich the information display of the visual interface.

The application provides a piano new score simplification method, system and simplified score, which changes five lines into four lines, and the piano new score simplification method comprises the following steps: receiving and analyzing a standard MIDI file to obtain original note information, a key signature and beat information; generating a simplified score based on the original note information; the simplified score comprises at least four basic stacks, and each basic stack corresponds to an octave area of a piano keyboard; wherein each basic stack comprises four equidistant parallel lines and three spaces between the four parallel lines, so that each line and each space in the basic stack corresponds to a white key note in an octave area of the piano. No horizontal line is added above or below the stack, which is very simple. In the above technical solution, the difficulty of reading a score during piano learning is reduced.

Claviation is a method for transposing an electronic musical keyboard in real time, supporting key changes during play using the keys themselves. A performer enters transposition mode via a pedal or button and then presses two keys in sequence to define the transposition interval. These two presses are muted so they do not affect the musical output. The three-step action can be executed within the duration of a beat and becomes faster with practice. The method requires no calculation or conceptualization of intervals. It allows scales to be played primarily on the white keys, even across key changes, eliminating the need to learn multiple key signatures and fingerings. A piece learned in one key can thereby be performed in all keys. The method accelerates learning, supports improvisation, and preserves spatial playing patterns across key changes, improving accessibility for performers and composers.
