Frequently asked questions
What is the major scale formula?
Whole, whole, half, whole, whole, whole, half (W W H W W W H). In C major, that gives C, D, E, F, G, A and B, with no sharps or flats.
What are the modes?
They are the seven scales you get by playing the major scale starting on each of its degrees: Ionian (the major scale itself), Dorian, Phrygian, Lydian, Mixolydian, Aeolian (the natural minor) and Locrian. Each one has its own sound.
What is the difference between pentatonic and blues?
The pentatonic scale has 5 notes, without the half steps of the major or minor scale, which makes it easy to improvise with. The blues scale is the minor pentatonic with one extra note, the diminished fifth (the blue note).
