Can concur as a bass player. Tell me to play (for example) a B and without even thinking, my hand will move to the second fret on the A string. Put a flat sign on it and I just move one fret down.

I also know the "shapes" of intervals though, and they are constant. A half-step is always one fret, a whole step is always two. A minor third is a minor third is a minor third: one finger on fret N of string M, the other finger on fret N-2 of string M+1; the names of the notes are irrelevant.

I pulled my flute out of its case after over five years, and within minutes was playing all my scales, and able to play the melody lines out of a hymnal. My tone was awful, and my lips got tired long before my hands.

To this day, I still associate flute fingerings with music I read for singing.

Or piano, which gets messy…
