How do you you sign rock music in ASL?

In American Sign Language (ASL), "Rock Music" can be signed by combining the signs for "rock" and "music." To sign "rock," use a fist with your dominant hand and tap it against the palm of your non-dominant hand, which is also flat. For "music," you can sign by placing your dominant hand in a flat "B" shape and moving it back and forth in front of you. Together, these signs convey the concept of rock music effectively.
