I believe that aural perception has helped me quite a bit. I know i can read music better and understand it a lot more. My study habits have not been amazingly improved for studying ap. But i get to the piano and play some things every once in a while. One thing i do enjoy is that i listen to music and critique it more. (Figure out the time signature, melody lines and things like that) I have gained a better understanding definitely. I think the exercises on rythm and melodic intervals we have done in class have helped me a lot
