There are many definitions of "learning";

If learning means reading music, playing the main rhythm of common pop songs (coordination can keep up), adding some flowers and playing a song completely, then the coordination ability is very good, and you can learn it in ten days at the shortest; If you have good coordination skills, it will take one month (if you have dealt with such students).

If learning refers to all kinds of basic skills (not very fast), all kinds of music styles will have a common main rhythm, have a certain inventory of flower spectrum, can pa spectrum, and can write their own main rhythm and flower spectrum, which is very tasty. It takes several years, and it takes several hours every day. This is not supported by exact data (at least three to five years).

Not only drums, but also other musical instruments are updated quickly. It's good to taste the sweetness and achieve the expected goal ~
