Music is a vast topic, and if you want to start with music, you first need to figure out which type of music you are interested in for performing and will move forward with it.
The best learning is self-learning. There is absolutely no proof that says you can’t learn music by yourself or you need to go to a music school.
You can start with your own, or if you didn’t know how to do something, check up online and google it. Whether it’s how to make a beat or add a new audio track, you can find every answer online, it might not always be the most pleasant, but it’s an excellent method to learn.
