Embodiment 1
[0026] A piano automatic performance teaching system, including a piano, an automatic performance system is arranged in the piano, and the automatic performance system performs any one or a combination of the following steps:
[0027] 1. Play the piece more than once in the normal way as a demonstration; record the content of the course as a MIDI and / or audio file. Among them, the MIDI file is used to control the automatic performance system to perform, and the audio file is used as an accompaniment to play synchronously in the form of sound.
[0028] 2. Play music in a rising or falling tone as a guide for teaching; performers follow the automatic performance of rising or falling tones and perform in a normal way, that is, perform in a way that does not change the pitch. So that beginners can quickly master the skills of playing.
[0029] 3. Play a part of the music, and the performer plays another part of the music as an ensemble demonstration;
[0030] Through the above s...
Embodiment 2
[0041] On the basis of embodiment 1, the performance data of the player is collected by the optical sensing device, and the data file is generated in the master control device; the master control device in this example preferably adopts a single-chip microcomputer with a memory chip. The interaction between the piano and the performer is realized through the comparison of data files. The generated data files can be transferred to a computer, mobile phone or tablet device through the USB interface, and the program can play them directly. At the same time, standard data files can be played to facilitate comparison of differences. The standard data file in this example refers to the data file generated by a high-level player, or the data file with the best performance effect directly generated by digital technology.
[0042] Preferably, the data files are MIDI files. In higher-precision MIDI files such as 128-bit and above, scales, notes, rhythmic intervals, sustains, and pitch ...
