Music Intervals - Theory Introduction for GuitarRemember:
A major scale is a pattern of eight notes in alphabetical order that produce the familiar sound:
The starting note (Do) is also called the Root note (1).
Each one of those notes is referred to as an interval. An interval is actually the distance from the root note or (1) to another note.
When talking about intervals there are three that are constant. They do not change whether the scale is major or minor. They are referred to as “perfect”, say a “perfect fifth” for example.
These intervals are:
The Perfect Fifth
The Perfect Fourth
