Intervals - the distance between two tones

Now we will look at building intervals. First we need to know what the term interval actually means:
An interval is the distance between two tones. It's as simple as that. So the interval of a 2nd is two half steps (or one whole step), a 3rd is two whole steps, a 4th is two whole steps and one half step (figure 1)

C D E F G A B C

1  2  3  4 5  6   7  8

In other words, from C to D (1 to 2) is a 2nd, C to D (1 to 3) is a 3rd, C to F (1 to 4) is a 4th, etc. This is where the scale degrees come into play.

Next time we will venture into building chords.
