Crotales (/ˈkroʊtɑːlz/, /ˈkroʊtəlz/[1]), sometimes called antique cymbals, are percussion instruments consisting of small, tuned bronze or brass disks.

These are bronze cylinders in the rough shape of a bull's testicle, with a piece of baked clay or a pebble inside.

Other classical pieces featuring crotales include Claude Debussy's Prélude à l'après-midi d'un faune, Maurice Ravel's orchestration of his Alborada del gracioso and Henri Dutilleux's Cello Concerto.

[3] The contemporary American composer John Adams uses them in many of his more colorful orchestral pieces such as Short Ride in a Fast Machine.

Wilco drummer Glenn Kotche uses them live on the Yankee Hotel Foxtrot song "I Am Trying to Break Your Heart".
