What each note does
- E♭ is the root. It names the chord and is the note your ear hears as home.
- G♭ is the minor third, a half step below the major third (G). That one note is the whole difference between sad and happy.
- A is the flat fifth. It pulls the chord tight and unstable, which is why diminished chords want to move somewhere.
