Abstract.Why is it that scales beginning with an A note feel sad? Seven-note scales are composed of five whole tones and two semitones. The position of the semitones determines whether the key is major or minor. Not all music in a minor scale necessarily sounds sad, but the arrangement of notes in major and minor scales plays a large role in determining the mood of music.
