Various proponents of CCM have dismissed passages such as Exodus 32 from being relevant to the CCM debate for differing reasons, including because there is no mention of musical instruments in the passage. I believe that factoring the ability of humans to mimic percussion instruments vocally, as in the contemporary practice of beatboxing,1 substantively changes the discussion of Exodus 32 and many other passages in Scripture that have often been debated in discussions about musical styles and their propriety in Christian worship.
1 Wikipedia explains beatboxing as follows:
Beatboxing (also beat boxing or b-boxing) is a form of vocal percussion primarily involving the art of mimicking drum machines using one’s mouth, lips, tongue, and voice. It may also involve vocal imitation of turntablism, and other musical instruments. Beatboxing today is connected with hip-hop culture, often referred to as “the fifth element” of hip-hop, although it is not limited to hip-hop music. The term “beatboxing” is sometimes used to refer to vocal percussion in general (https://en.wikipedia.org/wiki/Beatboxing; accessed 11/28/16; 9:53 pm).
