Chords Relative To Am9

Hey.
Just been playing around with the chord of am9, trying to work out some of its relative chords. Can anyone help me out with either of these things?
Thanks

I can't help but I'm very interested in some info on this myself.

The Am9 chord is basically an Am7 chord with the added 2nd note from the A natural minor scale (Aeolian mode). The 2nd note in the Am scale is "B". The reason the chord is referred to as Am9 is for tonal value, but the 9th is the same note (B) as the 2nd, an octive higher. To figure out the relative values of the Am9 chord, look at it's make up. Am9 = 1-b3-5-b7-9, notes A-C-E-G-B
Right away you can see that all of the notes are natural (no #/b's). So, we know that C Major it's cronies are a given.
C Major = C-E-G
C6 = C-E-G-A
CMaj7 = C-E-G-B
CMaj9 = C-E-G-B-D (D works because it is a Perfect interval (P4)of A)

there's more but You get the Idea, what else works beside C?
G Major = G-B-D
Dm = D-F-A (F works because it's the b6th of A natural minor scale)
Em = E-G-B
FMaj = F-A-C
Bm/b5 = B-D-F (used rarely by some because it's a diminished chord)

Although there are more than stated, You can see the relationship.

What about FMaj7 or FMaj9, would they fit?

Would EMaj7?????

well amin 9 has the notes

root A, minor third C, fith E, flat seven G, and 9th B.

it is possible to build several scales from these notes, but they must contain the above.

yopu could be in A dorian, notes A, B, C, D, E, Gb, G.
or could be A Aolian, A, B, C, D, E, F, G

or some more exotic scales.

from theses scales you can build a multitude or different chords.
if you want the nith chord, start on any note (other than A cos u already know that). and find the first note third note, fith note seventh note. then go back and get the second note, but make sure it is higher than the seventh.

eg in a aolian, take second note b. sp we have a chord of b d f a c/ which is b half diminished 9th (i think).

or in a dorian take second note b, we have b d gb a c. which is b minor 9 flat 2.

note the fith note is not that important in the chord and is often omitted.

hope this helps
