Now we will learn about intervals in more depth.

Intervals have a degree, or number, and also a quality, usually Major or Minor.
For example, a Minor 2nd has a quality of Minor and a degree of 2.

We learned already that the degree is determined by counting the number of letters between the two notes in the interval.

The first note is always counted as one.
For example, from C to E would be a third.

Major intervals are one half step larger than Minor intervals.

Major intervals usually have a happy sound, while minor intervals usually have a sad sound.
We will discuss more later about how to know if an interval is major or minor.
