I appreciate where you are musically.
I can see after having written this a year ago that certain things which could draw it together are missing.
There is no strong melodic line; just bundles of fragments which are
interwoven with various tone colors. I like the variable instruments which enter and depart: The piano part is the connecting link: the timpani signals a division of first and second half.
Perhaps to listen without a microscope as if listening from afar would
I'm still not sure about which is the largest performing venue in the ambience. Does it go from top to bottom. Some are obvious but I don't know which is the largest.
That seems to be important in just how the revereration takes place.
I liked this - the piano obbligato is very effective. The low brass is a nice quality, as well. The harmonic language seems consistent and - I use this word a lot - organic. By that I mean each sound makes sense in relation to what precedes/follows it. I guess my only criticisms would be, perhaps, a more defined climax, and a clearer ending - or a clearer preparation for the ending.
The reverb? Who knows - too many knobs to adjust...kidding, of course; but from what I've read, and by other posts here, it can be a whole world of learning. Take these comments as small ones. The big picture is that this is a very enjoyable. Glad you posted this!
