No, major 5th chords do not exist. 5ths are in the group of perfect intervals along with Perfect 4ths, octaves, and unisons, so calling anything a major 5th will be awkward. Chords called major triads automatically have 5th's. There is no need to say Major 5th: just say Major. Ex: C Major Triad = C = C E G = x320xx, C Minor Triad = Cm = C Eb G = x310xx. You may have heard of Major 7th chords, but that Major refers to the 7th not the chord quality. The chord quality should always be assumed major or noted as minor. Ex: Cmaj7=C E G B=x3200x, CmMaj7=C Eb G B=x3100, All unmodified 7ths will be a minor 7th. (Seventh chords are virtually impossible to play in closed position, so I will write them as used.) Ex: C7=C E G Bb= xx(10)986 =G E Bb C= 3x231x, Cm7=C Eb G Bb= xx(10)886 =G Eb Bb C= 3x131x. |

I don't think that they are technically either chords or major, but power chords are simply the tonic and the perfect 5th. They aren't major or minor (I believe) because they don't have a 3rd. |
