What's a fish's favorite instrument?

This joke is a classic example of wordplay, specifically a pun that uses homophones. The humor comes from the unexpected twist created by two words that sound identical but have completely different meanings. In this case, "bass" can refer to a type of fish, like a largemouth bass, and it also refers to the lowest-pitched instrument in the guitar family, the bass guitar. The setup leads you to think about aquatic creatures, while the punchline cleverly steers you towards music.

The bass guitar itself has an interesting history. While early versions existed in the 1930s, the first mass-produced electric bass guitar, the Precision Bass, was introduced by Fender in 1951. It quickly became popular, replacing the larger and less portable double bass in many genres like pop, rock, and jazz, providing the rhythmic and harmonic foundation (Review) for countless songs. As for fish and music, while they don't exactly "play" instruments, some studies suggest fish can perceive sounds and may even react to certain types of music, with soothing classical tunes sometimes played for them in aquariums. So, while a fish strumming a bass guitar is pure absurdity, the wordplay makes it a delightful little chuckle.
