Intervals: Let's talk relationship (page 2 of 2)
So what’s the name of this interval?
If you said "eighth," you got trapped by my trick question. We call this an octave. (“Oct,” of course, means “eight.”) Do you notice anything interesting about two notes that are an octave apart?
Right--they have the same name. When you travel an octave you end up at the same note at a higher or lower level.
Keep in mind, too, that a second is also called a step. Each name has certain advantages, so you'll need to remember both.
