An interval measures the distance between two notes.

We will first discuss generic intervals, which are measured on the staff.

When two notes occupy the same line or space, they are a first (or a prime) apart.

C to C is an example of a first.

C to Cb and C to C# are also firsts.

When two notes are askewed to each other, they are a second apart.

C to D is an example of a second.

C to D#, Cb to D, and Cb to D# are also seconds.

When two notes are stacked tightly together, they are a third apart.

C to E is an example of a third.

E to G and F to A are also thirds.

As the notes become further apart, their interval type increases.

C to F is a fourth.

C to G is a fifth.

C to A is a sixth.

C to B is a seventh.

C to C is an eighth (or octave).
