The Hazel Woods waltz

A lovely air from Declan Masterson’s peaceful CD Drifting Through The Hazel Woods. I haven’t a clue, to be honest, about time signature etc. It being an air it is rather more difficult to impose a signature and bars on it. I’ve really only written the notes and ornaments down (slides not appearing but being shown as J in the notation) seeing as how no air can really be played off the page without listening to it. Someone more capable than myself is welcome to tinker with it and get time signature, note length and bars sorted out more accurately.

I think it the key should be E minor?
