Why it sounds like that

E♭ augmented major 7th is built from the formula 1, 3, ♯5, 7. The augmented 5th, B, is what separates it from the E♭ major 7th, where the 5th is B♭. The major 3rd and major 7th remain unchanged.

What goes wrong with E♭ augmented major 7th?

  • Letting the low E string ring instead of muting it.
  • Letting the B string ring instead of muting it.
  • Fretting the high e string with the ring finger instead of the pinky, causing the note to go flat.

When to use it

E♭ augmented major 7th works as a substitute for E♭ major 7th when the melody moves to the ♯5. It fits jazz ballads and passages that need a brighter, more restless major sound.

Changing to and from E♭ augmented major 7th

  • Sliding the shape down one fret to the 4th fret gives D augmented major 7th.
  • Sliding the shape up one fret to the 6th fret gives E augmented major 7th.

Which voicing to use

The 5th fret voicing keeps E♭ in the bass and is the default. The 9th fret voicing repeats the same shape an octave higher, while the E♭augM7/G inversion on the 1st fret puts G in the bass.

What is the difference between E♭ augmented major 7th and E♭ augmented?

Why does the B string get muted?

The B string is muted to preserve the intended voicing, not because it clashes. B is a chord tone, but playing it would change the bass note.
