Baritone's larger cousin (4)

I believe the answer is:

tuba

'baritone's larger cousin' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for tuba that I've seen before include "Brass band instrument" , "Musical instrument -- 5 (rev)" , "This loud instrument" , "Producer of note" , "Big brass instrument" .)

I've seen this clue in the Universal and the USA Today.
