The circle and the chart are helpful. Another important concept is what's called "the scale pattern," or, the "intervals" of the scale. Major, minor, pentatonic -- each octave has a specific pattern of intervals.
A full step interval is two semitones. For example, C to D in the C Maj scale is a full step (two frets.) A half-step interval is one semi-tone, (one fret) e.g. E to F or B to C. There are no E# nor is there a B# in the C Major scale. -------------
Full step: C (the one) up two frets to (the two) D.
-------------------- C Major Scale: ----------------
C (root) - D (full step up) - E (full step from D) - F (half step) --
G (full step) -- A (full step) -- B (full step) - C (half step)
------------------------------------------------------
Apply the same principles to all 12 keys of the major scale.
Root (First degree of the scale, names the key. Step pattern:
Root - whole - whole - half - whole - whole - whole - half
--------------------------
Thanks for catching those mistakes, Dave Snyder. I hope I made the corrections. Apologies to all.
