The basic major scale is usually presented as a C scale: C D E F G A B C
But you’ve probably been playing other major scales such as G: G A B C D E F# G or D: D E F# G A B C# D
The trick to understanding the similarities between scales is that a scale isn’t based on the notes themselves but on the distance between the notes. This distance is called an Interval. Intervals can be various lengths. On octave is an interval. A fifth is an interval.
They call a single fret a half-step. A whole step is two frets.
It only has seven steps because that’s all we need to get to 8 notes.
Here is the scale in frets: 2 2 1 2 2 2 1 frets
Thinking of the major scale in intervals shows how they are all the same except for the particular note they start on.
Here are all the major scales. They are shown how they are often represented. A Db isn’t usually written as C#. F# and G# sometimes are written as Gb and Ab, but string players tend to think in sharps (if they think about that sort of stuff at all).
