It is easy to learn, but difficult to learn well. The cost depends on the instrument you learn and the level of learning. For beginners, a lesson at a piano store will probably last from 45 minutes to an hour. Once you learn more, your level will improve. The price will rise. Learning from an individual teacher is more expensive, about 100 to 200, but the quality is higher than that of a piano store. If you want to continue your studies, the cost will be higher. There are lessons of about 500 to 600. The same goes for vocal piano.

If you learn an instrument alone, you can probably only work as a teacher in a music store. To study music professionally, you also need to learn music theory, harmony and other knowledge. Can work as a composer or performer.

Anyway, I just want to learn how to be cheap. If you want to eat, you have to spend money
