To put it simply, melody memory modeling is to build a melody (which can be long or short, such as an eight-bar melody) according to the sequence, such as playing some notes with a piano at a certain speed and rhythm. For example, just listen to it, such as 1~3 times, and then let you build a model (such as singing the word LA).

What score do you need to understand in solfeggio? It is best to read both the music score and the staff. Piano music is generally a staff, and guitar also has a mechanical staff, so let's not talk about anything else.

In addition, there are guqin, guzheng, flute, erhu and pipa. Although they all use simple notation, they all have their own characteristics and different symbols. I hope you have a clear idea. I don't know if my answer is reliable.
