Music by ear or notation?

A strange question in my opinion. How can strangers tell you what is necessary for you or not? You seem to know the answer yourself already. If you know that you lack theory aspects, then learn them.

But keep some theoritical knowledge it will just boost up your tallent. You may be able to learn and understand music faster.

i think by ear

Wow. Without learning you can play? Surely that's a God's gift

Music by hearing is for me. I feel like its difficult for me to read notes. I am not good at notes.

Keep practicing hearing and playing. It is the most important quality needed to play any instruments. If you can play a music by just listening then don't worry, you gonna rock

That's great talents and skills, David. And, every musician should have good musical ears. So, there is no tone deaf, missed tones or wrong routines or practicing a piece or song. There are pros and cons to just using only by ear. And, as well as the ability to musical notations only, there are also pros and cons. So, why not do the same. Do by your musical ear abilities and do notations also as well. But, yeah, it is hard to be done. Once you practice that one, you can do the other, because of too much comfortable. But in case you really need it, just do it confidently. I myself play piano/keyboard/guitar but I'm more on notes and chordings. I can memorize some, but not more or many. For self-satisfaction only. Not been on jamming sessions.

I've actually done both - play by ear and read. I think there are advantages to either of the ways. When you can do both, then you are increasing your musical horizons.

,,,just do.what you can do.best.. ive known musicians that dont read notes.but can play a piece just by ear...
