Boccherini: Duet for Two Violins
Expressive, yet lacks the slow paced build at the begining.
Sad, Slow & Expressive yet there not enough tempo change. Lacks dark tone.
I feel as though this next piece however, is the only one a came across that had everything I was looking for, emotion, dark, sad, cold, nicely paced, and beautifully soft sounding. I'm not going to lie, I've struggled trying to describe what it is I'm looking for, but this piece answers all my questions to put it bluntly.
Chopin: Nocturne, Opus 9 No. 1
This is my clear choice and the more listen to the piece, the more it makes sense. Its true however now I've decided on this piece, I need to properly analyse the song, considering what imagery it may convey, also understand how to incorporate my own style and animation/visual idea's with it's tempo and tone. All the while sorting on the relevant license to use it legally.
Here are some of the sites I've gathered whilst trying to find my sound.
