Before we do, however, we need to talk a little bit more and how scales and intervals are related.
The first note always counts as 1.
For example the quality of a Major 2nd is Major.
|Perfect 4th – Chord|
|Perfect 5th – Chord|
|Octave – Chord|
This includes 2nds, 3rds, 6ths, and 7ths.
Intervals are called “minor” if they are one half step smaller than the interval found in the major scale.
In common speech they are sometimes called “flat”. For example, a “Flat Third”.
For example, a Diminished 5th.
- The degree of an interval is based on how many steps one must take in the scale to get there.
- 4ths 5ths and Octaves are generally called Perfect because of their pure sound.
- 2nds, 3rds, 6ths, and 7ths are called “Major” if they line up with the Major Scale.
- If a major interval is lowered, it becomes minor.
- If a perfect interval becomes lowered, it becomes diminished
Now apply what you have learned.
