What I don't get about uprights is the notation. You start with bass clef, at about high D (like 7th "fret" on the G string) they start writing in tenor clef, and thumb positions are usually in treble clef. I just can't get used to it.
A bass guitar has the same number of notes and when you go up the neck and want to avoid too many ledger lines, you write "8va" and write an octave below the fretted note. Simple and effective. Why do classical players use 3 clefs for a 4 string instrument? I just don't get it.
