Pretend an amplifier where open loop does not behave as it was affected to closed loop. Scare? The where same happen with music. If you are musician then your definition, you feeling of tempo and timing are greatly modulated by reverberation time at the performing space. If you need to hit two keys on piano with an internal (let present that it is the Beethoven’s Sonata no. 8) then how long the internal would be? The duration of the internal is very important but it is also very important the organization and the reaction of the rest of your play to those internals. That organization is the product of musician awareness and the reverberation time is one of the ingredients that affect the musician compliance. Changing the reverberation conditions without changing the “musician compliance” is not good thing to do/



You are quite right about this - music performance is a feedback system via the ears.

Also, in the same way, equal loudness related hearing non-linearities mean that by altering the loudness of the playback we take tonal (spectral) control away from the musician.

Further to this, on the subject of reverb perception, given that the threshold of hearing varies according to equal loudness effects (not linear with frequency), alteration of playback SPL will also affect perception of reverb directly.

Specifically, (simply speaking) where we listen at SPL above that of the actual event, we will perceive greater amounts of (longer) reverb and where we listen at SPL below that of the actual event we will perceive lesser amounts of (shorter) reverb.

Also, where equal loudness effects alter the spectral relationship between direct & indirect sound we can expect the auditory masking relationships to be affected.
