We've already given a good listen to the interval in episode 10. Let's add one more note to it and hear what the triad sounds like. We will discuss the sonic characteristics of the four basic triads: major, minor, augmented and diminished and their inversions. We will also stack on one more note and briefly talk about the standard basic 7th chords: major major seventh (M7), major minor seventh (Mm7 or the dominant 7th), minor seventh (m7) and even the elusive minor major seventh chord (mM7).
