Grumio
Petruchio
[He wrings Grumio by the ears. Grumio falls to the ground screaming]
After “ringing” the door (using the metal knocker), Petruchio wrings, or twists, Grumio’s ears until he “sings” out. To “sol-fa” means to sing the musical scale: do, re, mi, fa, so(l), la, ti, do. Petruchio is also making a subtle pun; the verb to sol also meant to seize an animal such as a rabbit by the ears.
