And this brings to mind another point often made, that I never understand...at all. Something like: 'You don't have to look at the fingerboard of a fretless, you just use your ears to stay in tune'.
Well, how the heck are you going to do that, if you're often playing a bunch of eighth, or sixteenth notes? How is there any time to 'ear your way' into intonation, when you're only on the note for a split second.
If someone can explain how this can be done, I'd love to hear it.
Agreed. You hear all about pitch correction, assuming you have time to do that. While the intonation is slip sliding away...
