Hello,
I have been hearing this in my head for days. It starts with the clean full notes of a single instrument, a french horn or a clarinet, possibly? In my mind it plays through this 13 note theme, then more instruments join. I've searched and searched because it makes me feel like the day is dawning. and maybe that's where it's familiar to me, from a movie or something? It's just so beautiful and dainty then powerful. Just thinking about this and how it makes me feel has me realizing I should be listening to more classical music.
I used the Les Paul's 96th Birthday Google doodle to record the sequence one time through. Forgive my lack of basic knowledge to get it to you otherwise...
It's all major keys if played on this scale.
