What would the electric guitar was not invented?

If the Electric Guitar had not been invented, the landscape of popular music would likely be vastly different. Genres like rock, blues, and metal might not have emerged or evolved in the same way, relying more on acoustic instruments. The absence of the electric guitar could have led to a greater emphasis on piano, brass, and string instruments in popular music. Overall, the sound and energy of contemporary music would be significantly altered, potentially stifling the creative innovations that followed its introduction.
