Yes indeed. Sorry if I was unclear in my wording...I meant:

* Fretted cellos would have the same fingering positions as unfretted cellos (frets are placed where the notes are, they don't set where the notes are).

* All parallel-stringed instruments have modular fingering patterns like this (though not exactly the same fingering patterns, if their string interval differs) so this is a good principle to try no matter your instrument.

Learning both guitar and cello is kind of like learning both QWERTY and Dvorak. Same intellectual principle, whole different muscle memory.
