LET’S GET PHYSICS-ILL

Dear Gents, I need a pun that incorporates the sciences and music. Preferably from the current pop culture or maybe rap/reggaeton. ~Jazmin, La Jolla, CA

AS THE PUN GENTS SEE IT:

1. Math-ter P
2. Yo G = 9.8 m/s²
3. The law of afro-ges?
4. When you combine Beethoven and Mozart, what do you get? Moz Deaf
