Yes, whoever said that musicians are good at math (or have to be good at math) is lying. I am not horrible at math but I'm not the greatest at it. I overall am not the most academically inclined but I do really enjoy English and have taken advanced placement English and English literature simultaneously at school.music teacher said:""you need to be very good at math to be successful in music."" no, you don't, and in fact, except in very rare exceptions, good musicians and good music students are good at English, unmechanical, and poor at Math and sports.
The degree of Math involved in learning Music is tiny, and is limited to beats and rests.
