From the beginning to the end this one sounds "round".
I can imagine this to fit as some kind of intro/ambient music for a mystery/detective show. But also this somehow transports the notion of farewell and sad feelings connected to this.
When music is able to make me feel/think just by listening to it, I consider it to be stimulating and in this case it is what makes me give you 5 stars.
Thank you for this contribution!
