I started playing piano last year teaching myself how to play by just listening to songs i liked and tried to copy them on the piano. For some odd reason i could pick up certain pitches with my ear and melodic melodies everytime i played different notes. I had no idea why some notes sounded awesome together and why others did not. My music teacher taught me why the notes i played went well together. 440Hz is an important number to any musician because that is the frequency that everyone tunes to, which is the note A. Different notes have different frequencies. I would always play in different ocatves, but never understood there relationship. In physics i learned that octaves are differentiated by factors of two. In the picture my left hand is playing a G2 and a G3, the frequency for G4 is 396Hz so if i divide that by 2 i get 198Hz which is the frequency of G3 and i divide that number by two again i get 99Hz which is G2. Understanding the frequency of octaves and different notes has expanded my creativity and caliber on the piano. Who knew how mathematical music is?!!!!
