Hi Djim,

Sherry's right, I think. There's not enough of the piece to establish a key. It might be in C, and begins with the tonic chord with an added minor 7th. (The Eb doesn't really count because it's a grace note leading to a natural E.) In fact the whole example contains tones in a C chord. Or it could be in G minor and begins on the sub-dominant chord, a C with a minor 7th. I think the chord analysis above the notes hints at the ambiguity. There doesn't seem to be any particular reason that the G's in the bass should be considered parts of a G minor chord.

I guess for me the important thing is that, so far, it sounds pretty good.

all best,
