Fret Not If Your Guitar Doesn’t Perfectly Intonate Up Down The Fretboard

[TalismanRich]

Surely the nut thing only helps with open strings and it totally defeated by a capo?

My son was told by the guy that made his classical guitar that 'heavy fretting' makes thing sharper and to use jeeeust enough pressure to stop rattles. Fiddle and other fret less players of course can find the perfect note IF they are good enough! But then they cheat a bit with the wobbling. Even that has its downside I have read? A violinist playing perfect intonation against a tempered keyboard can sound weird?

You typically tune on the open strings, so it changes the pitch slightly with a slightly different scale length. Earvana has some information on how it affects the tuning process.
