Notation Manual section 1.1.2 under "Transpose":
"This means that musicexpr is transposed by the interval between the  
pitches
frompitch and topitch: any note with pitch frompitch is changed to  
topitch and
any other note is transposed by the same interval. Both pitches are  
entered in
absolute mode."

Note that the "frompitch" and "topitch" are entered in absolute mode.
