One of my favorites for a solo trumpet was to back the volume down and add a little brilliance. It wasn't any louder, just seemed more present and was easy to focus on.
Do your ears inter-modulate and produce other tones.
Why do high volume bass tones seem to compress music?
Did you know speaker systems have a doppler effect.
So, how do you blend instruments?
