Those are good questions! Resolution is definitely less when it comes to music - I can hear obvious signal degradation when it comes to somebody talking through a bad phone reception for example, but the difference between a high-def mp3 and a low-def mp3 is near indistinguishable.

I don't -recall- hearing half tones but that may be because I avoided classical music out of personal taste and after a childhood of mandatory piano lessons... it's been a while since I've gone near an instrument. Amusingly picked up a strong fondness for 80's synthpop/EDM/industrial which feels like it could be partially explained by it being 'beat heavy' and less delicate/subtle with different instruments. Would be a fun study!

edit: Jumping back to explain that resolution/quality vastly varies from person to person, even if they're using the same generation of devices - to make a long story short, CI's hook up to electrodes within the ear, and the more electrodes that can be sync'd, the better the resolution. Mine was an odd case where I have a facial nerve right next to a cluster, and those had to be turned off otherwise it would cause my face to twitch excessively whenever a certain pitch of noise was played.

There's also single-implant users and bi-lateral implant users - most folks these days opt for bi-lateral as you do get a whole 'nother level of quality; I was one of the early bunch and have other medical complications that make another surgery very difficult, and decided that since the single's been fine for daily use, it's worth it just to stick with it.
