Title: Help on chords
Post by: Emeline on August 30, 2006, 09:11:25 PM
Can anyone please clarify the following questions:


1) Bb maj7:

   R.H: D G C (Bbmaj7 notes are Bb D F A without G & C, how come these two notes are played in this case?)
   L.H: Bb


2) Eb7(b9)

   R.H: G C E (How come C is included in the chord ? )
   L.H: Eb Db

3) Ab6/9

    R.H: Bb Eb (Bb should be A ? coz b9 = Bbb = A?)
    L.H: Ab C F

Where did you find these chords at?

The is chord should be called a Bb13 not a BbM7.  If you stack the notes in thirds, you should have:  Bb-D-F-A-C-E-G   It's missing the C and the E, but it's still considered a Bb13 chord.

   R.H: G C E (How come C is included in the chord ? )
   L.H: Eb Db

This chord should be called an Eb13, not an Eb7 (b9).  If you stack the notes in thirds, you should have:  Eb-G-Bb-Db-F-Ab-C   It's missing the Bb, F, and Ab, but it is still considered an Eb13 chord.

3) Ab6/9

    R.H: Bb Eb (Bb should be A ? coz b9 = Bbb = A?)
    L.H: Ab C F

This chord is correct.  It is an Ab major chord with an added 6th and added 9th.  If you stack the notes in thirds, you should have:  Ab-C-Eb-F-Bb


Does that answer all your questions?  Any other theory experts can back me up to make sure all this is correct.
