growl

Hardly anything is more intensely disagreeable to one walking along the street, than to hear near his path a low savage growl—the expression of a surly dog's opinion and purpose.

Riding down the main thoroughfare, the growl of his stomach taints the soothing jazz playing on the radio.

The clerk promised that he would; and Scrooge walked out with a growl. The office was closed in a twinkling, and the clerk, with the long ends of his white comforter dangling below his waist (for he boasted no great-coat), went down a slide on Cornhill, at the end of a lane of boys, twenty times, in honour of its being Christmas Eve, and then ran home to Camden Town as hard as he could pelt, to play at blindman's-buff.

The growl effect comes from fitting a small straight mute—a cornet mute for trumpet and a trumpet mute for trombone—covering the instrument's bell with a rubber plunger, the kind used by plumbers, and moving it in and out to affect the tone.
