Last post, I talked about music and how it's just air vibrations, but I didn't get into what constitutes good music or what just doesn't sound good. "Good" music usually contains harmonies, which basically add another layer to the music. These harmonies are notes at one of the melody's harmonic frequencies. These notes amplify the melodic sound and have a resulting pleasant sound to our ears. On the other side of things, there are some notes that just don't sound good together. These are notes t

What can we do to make them better? If yo
