Game Mechanics: Issue with Bard songs and missing notes.

[Lazortag]

This has gone on for long enough that I know it just can't be coincidence. I have my singing skill past 200 and find that I'm missing just as many notes as when I was level 1. I'm not sure how often I miss notes when I actually have an instrument in hand, but I know that when I'm in a group (which usually means I'm dual-wielding), I miss notes so often that it's become quite difficult to consistently 4-twist songs. This doesn't mean I never 4-twist, or that I don't succeed in 4-twisting the majority of the time, but that I'm unable to consistently do it because of the annoying (and now predictable) missed notes I keep getting.

There should probably be a more noticeable difference in the number of notes I miss with a singing skill of 200, unless I just misunderstand what a singing skill of 200+ is supposed to be good for?

Also I've heard Cha affects missed notes, but my Cha is at 134, which doesn't seem so low as to affect the number of notes I miss this badly.
