Ol' T
heory-block, Johnny on the spot, on the case again, pretty much answered it! lol
So my answer will basically serve as
at least partial
"verification" of what he already said:
I have a question I use these two chords in a composition I'm working on, however when going from the first chord to the second chord the key changes. I have done this in other composition and can figure out what key to solo in, but my question is what am I doing? I figure a little theory is in need.
These are the chords I'm talking about.
C/EGBD
C/FAbCEb
Could this be from listening to too much jazz?
Well first of all, i don't think you can listen to TOO much Jazz! lol...Cause you can never learn it all in a lifetime! lol
However, it seems like you simply played a
I-IV (1-4) progression, using the
5 instead of the
root as the bass note on the IV chord.
ex. 1: I-IV (1-4) progression with the
1 (or the root) as the bass on the
IV chord:I chord____(CM9) C / E-G-B-D
IV chord___(Fm7)
F / F-Ab-C-Eb
ex. 2: I-IV (1-4) progression with the
5 as the bass on the
IV chord:I chord____(CM9) C / E-G-B-D
IV chord___(Fm7)
C / F-Ab-C-Eb
As you can see, the
IV chord is an Fm7, and
the 5 of Fm7 is C.
In ex. 2, which is how YOU played it, you used C (or the 5) as the bass note instead of the normal F (or the 1 or the root).
Using the 5 as the bass is a (move or option) that is often used in music, and can sound nice and be quite effective, if used right, as you have evidently already discovered.
