In music, you hear it first, feel it second and learn it third. It's that simple. There is no music school in the country that can be relied upon to teach you music. On that third point, you learn it because you need to know it for some reason. Formal skills can cut down on the learning curve sometimes.

You can learn a song faster if you can read music. You can communicate with other trained musicians if you know the language. You can play different kinds of music with this knowledge easier.

Will it make you a better musician?

Who knows?
