So, I understand why classical strings (violins, cellos etc.) aren't fretted, because of the change this makes in the tone. I've often wondered though, why the note positions aren't marked on the neck anywhere.
Wouldn't notes relative to the open string be in the same place all the time? Wouldn't it be possible to start at a marked position and then adjust the pitch to match other instruments? Wouldn't even a chalked-on mark would make it easier to find notes?
Any clue why it's done the way it is?
Note the question is not “why don’t violins have frets?”
