About adults learning musical instruments

Keyboard, piano and accordion are common. Piano is very popular and it is not difficult to get started. It's convenient to carry the accordion, but it's a little tired for your arms and shoulders.

Blowpipe, flute and cucurbit silk are very suitable for girls. They are light and easy to use, and they can also practice their breath.

Strings, violins, erhu and other stringed instruments, it is a bit difficult to find notes completely by listening.

Guzheng and pipa are not very difficult. Etudes have the classical charm of China, which is very suitable for girls.

Percussion and dulcimer are very pleasant to listen to, belonging to folk music and easy to use.

It depends mainly on your interest. I started learning guzheng at the age of 22, because I had no interest in what I played. Now I can play band 6 music, mainly because I like it.
