I'm writing a song where the notes do not align to any particular key. The way it works is this
Chord 1 leads to Chord 2. Chord 2 leads to chord 3 but Chord 3 does not have to relate to Chord 1. Chord 3 leads to Chord 4 but chord 4 does not have to relate to chord 1 or 2.
It is a 16 bar chord progression and here is the progression:
Cmin - Gmaj - Dmin - Cmaj - Amin - Gmaj - Emin - Dmaj - Cmaj - Gmaj - EbMaj add9 - Fmaj sus4 - BbMaj - EbMaj - BbMaj - Gmaj
It is a little weird, but so far it works.
Does this have a definite key (or maybe 2 or three)? Or no and this is a truly fluid piece.
Also this loops - The final Gmaj goes back into a Cmin;
Finally, here is an audio file if this helps: https://drive.google.com/file/d/19XYlxpu3c4V_ohi-H9knjJ8k1LWWYscd/view?usp=sharing
