Do you need to memorize music scale in order to play any instrument?
In order to read music you will have to memorize the scales.
There are people out there though that can play by just hearing the
music and repeating it. Personally I think it limits you when you
cant read music. Good luck. You don't have to memorize scales to
learn to read music, however, it makes playing correctly in
the key easier. Memorizing scales is a overall part of musicianship
and understanding concepts of music. It also helps greatly if you
want to improv, especially in jazz music.
