Definition: A major scale is a series of notes characterized by its relatively happy and positive character. A major scale begins on a keynote, and follows the major diatonic pattern of steps:
I_whole_ii_whole_iii_half_IV_whole_V_whole_vi_whole_vii°_half_I (next octave)
Understanding the Major Scale Above:
- The uppercase roman numerals signify chords that have major thirds, while lowercase signifies those with minor thirds.
- The symbol ° indicates a diminished chord, which has a minor third and a diminished (or flattened) fifth.
See minor scale.
