+ 7 chord?

[Biglump]

Hi Folks,
I'm not getting very far in finding a sweet note to play for an Am+7.
I'm unsure of what the + actually means in this context?

Weird way of writing it, but maybe a minor 7 chord with a raised 7th? G# instead of G?

So: A C E G#

The + symbol I think can mean a raised interval (e.g. Cmaj7+11 = C E G B F#) but don't often see it used in that way cause it typically indicates an augmented triad (e.g. C+ = C E G#).

Do you have it in context of a progression? I might be able to give a more accurate answer

If it is an A minor with a natural 7 you can play notes from A harmonic (ABCDEFG#)or melodic minor (ABCDEF#G#).

I'd associate the + with an augmented chord so, although I've never seen a Am+7 before, I'd suggest Am7b13?

Try a sharp 5th

Try the harmonic minor scale.

The chord itself is created as a result of that scale. It's basically a minor chord with a raised (augmented) 7th. If you're playing a walking line, the 7th tone itself isn't that important here and it's not a hugely strong note anyway, so you don't need to labour the point. If you need something you could just use a minor scale approach, or do something more interesting descending chromatically from the root.
