Also, how do you identify the major vs minor vs perfect intervals. Do they have a "sound". Why are they named major, minor and perfect? Does perfect have a more pristine sound?? Does minor have a minor sound--- you know, that down tone that minor chords have. And lastly, do major intervals have that major-ish sound--> just the straight forward sound. How do you really recognize them b/c right now alot of them sound the same to me. Thanks guys!
