Music Theory - Intervals
Just as atoms are the smallest building blocks of matter, we can consider intervals the smallest building blocks of music. We need to know:
- What an interval is
- Where did it come from
- What it sounds like
- How to play it
It all starts with the major scale, remember this thing with the notes C, D, E, F, G, A, B, C
It sounds like this:
The distance between any two notes is an interval---so you need at least two notes to talk about an interval. The notes can occur one after another, like a melody ( which is how they appear below ) or they can occur simultaneously (harmony).
Here are the intervals between C and each other note in the C major scale. Lets figure out what the names mean: the number seems to indicate what scale tone is involved. In other words a Major 3rd is the interval between C and E, and E is the 3rd note in the scale. When you are ready for more, click on the More... link, below.
