Sound and Character
Major chords are the 'happy', stable triads of Western music. The interval of a major third (4 semitones) above the root gives them their bright, resolved character. Lowering the middle note of A♭ by one semitone creates A♭ minor. This comparison is one of the most instructive exercises in music — hear how one half step changes the entire emotional character.
