→Diatonic Intervals
As mentioned earlier, intervals can describe the combined sound of two notes as well as the distance between two notes. In a scale, the root note forms a basis point from which we can describe other notes by their distance from it. For instance, I could say to play the note a M3 above root then the note a P5 above the root. Ironically, we can use intervals to determine other intervals. For instance, the interval between the M3 and P5 above the root note is a m3.
--0----4----7--
|----M3 root +4 semitones is a M3 |---------P5 root +7 semitones is a P5 |----m3 the M3 to the P5 is 3 semitones - a m3
Let's look at the intervals from two different perspectives inside the key of C Major:
