Contrabass
Contrabass (from Italian:contrabbasso) refers to a musical instrument of very low pitch—generally one octave below bass register instruments. While the term most commonly refers to the double bass (which is the bass instrument in the orchestral string family, tuned lower than the cello), many other instruments in the contrabass register exist.
