Steely Dan Chords

This short lesson is about a type of chord that occurs frequently in Steely Dan songs and that is known to Steely Dan fans as the ‘mu major chord’ or the ‘µ chord‘.

Mu major is another name for an add 2 chord and is nothing more than a major triad with an added 2:

 

Mu chord formula:     1   2   3   5

(This type of chord is not the same as a sus2 chord because sus2 chords do not contain a 3rd.)

The add 2 chord is not invented by Steely Dan and many artists (notably Herbie Hancock and Roy Ayers) have been using this chord long before them. The manner and frequency Steely Dan has been using the chord in their music made the mu major chord a part of Steely Dan’s signature sound.

The name ‘Mu major’ itself started as a joke, the exact reasons for calling it that way are forgotten.

The main sound characteristic of the chord is the major 2 interval between the 2 and the 3. This interval has to be present because it is the essence of this chord’s appeal (Donald Fagen’s own words).

To hear the Mu major chord in action, listen to songs like Reelin in the Years (the intro) from the album Can’t Buy a Thrill or Deacon Blues (also the intro) and Aja from the album Aja.

The mu major chord is usually played on the piano in Steely Dan albums, but also on the guitar. These chords are much harder to play on the guitar than on the piano though.

In the words of Walter Becker:

 

“That’s something that I did where available on guitar. It’s always available on piano. We had Denny (Dias) do it on the guitar because he had far greater dexterity. But whole-tone dissonances like that are quite awkward on guitar except in certain open chord positions”.

    Thanks Marty, for that Gmu. Knew a fair amount of them but not that. What a marvelous sound.

  • Marty says:

    I like this rootless G mu major x2523x – works well in the Peg verse Cmaj7 (x3545x) to G mu

    • bob guyll says:

      marvellous,thanks for that inversion

  • Nicole says:

    I certainly agree with the statement that this type of chord is always available on piano. On guitar, it takes a high level of skill (and as mentioned above, dexterity) to utilize. On piano, I like this type of chording, gives a nice, full sound- particularly when playing solo. Thanks for posting!

    Also works great with 7th chords, minor chords.

  • brad benefield says:

    I learned this as an “add 9” chord – a major (or minor) triad with the 9th/2nd added, and no 7th. A couple of easy fingerings I use (not necessarily with the root in bass):

    G chord
    E- 5
    B- 3
    G- 4
    D- 5

    or

    E- 3
    B- 3
    G- 4
    D- 7

    or a D chord
    E- 2
    B- 3
    G- 2
    D- 2

  • Scott Perry says:

    Wouldn’t this fingering also work? (A mu major): 6th string 5th fret, 5th string 4th fret, 3rd string 4th fret, and 2nd string 5th fret (and if dexterous enough, 1 string open to get extra E ring). Seems easier to me, less stretching.

  • David says:

    Pls add the correct finger positions to make it easier.

  • Gerald Thornton says:

    also if you needed a chord for E mu major an easy enough “shape” that meets this criteria is
    e 2
    B 5
    G 4
    D 6
    A x
    E x

    • Peter says:

      Easy enough if you have long fingers, otherwise will take some stretching and straining for a while.

  • David says:

    I think it’ll be easier to play the chords if the correct finger positions are added.
