For the fretless folk out there

[drumsnbass]

We all know there is one, and only one, place to put your finger down to get the exact right note
(barring moving to another string of course).

how exact a standard do you hold yourself to, before you know everyone else knows you are off?

[Swimming Bird]

Define 'on'. I guess I'm anal, but one of my favorite parts about fretless is moving in the space between intervols. So I'm not always 'on' the note, but I'm where I intend to be.

Also, I like being a touch flat or sharp depending -- a little disonence can sound very cool.
