major scale

musical scale made up of eight notes (Music)

In music theory, the major scale is one of the diatonic scales. It is made up of seven distinct notes, plus an eighth which duplicates the first an octave higher. The simplest major scale is C major (figure 1), the only major scale not to require sharps or flats on the musical staff and consequently uses only the white keys on the piano keyboard: to the C major scale. When writing out major (and minor) scales, no line or space on the stave can be skipped, and no note can be repeated with a different accidental. This has the effect of forcing the key signature to feature just sharps or just flats; ordinary major scales never include both.
