A Major, Mixolydian Mode
Submitted by: Russell Ambrose
The order of Mixolydian tones and semitones is identical to the Dominant 7th scale. In other words, the C Mixolydian mode and the C Dominant 7th scale are identical. This modern scale has the same series of tones and semitones as the major scale, except the seventh degree is a semitone lower. The Mixolydian mode is sometimes called the dominant scale, because it is the mode built on the fifth degree (the dominant) of the major scale.The order of tones and semitones in a Mixolydian scale is TTSTTST (T = tone; S = semitone), while the major scale is TTSTTTS. The key signature varies accordingly (it will be the same as that of the major key a fifth below).
