That's it !!

(time to (re)read the fine manual, beginning to end)
THANKS!


Although, I must say: it's an awful choice of markup words, given the 
semantics at play:

"\transpose" to change written pitch

and

"\transposition" to change the audible, midi pitch

because they are noun- and verb-form variants of the same word, and the 
noun versus verb distinction somehow aligns with the audio versus visual 
distinction ... doesn't seem congruent or intiutive

(I did find the "transpose" command earlier, and realized it wasn't 
changing the pitch — only the written.)
