Question

How can you figure out weather or not an interval is perfect , major, or anything else

Answer 1

Answer:

Determine size (by counting lines and spaces between the notes)

Determine if the top note is in the major scale of the bottom note.

If it is: the interval is perfect (if it is a unison, fourth, fifth, or octave) or it is major (if it is a second, third, sixth, or seventh)
