There seems to be some confusion or misinformation regarding John Lennon’s first instrument. While John Lennon was indeed a talented musician who played multiple instruments, including guitar, piano, and harmonica, it is not accurate to say that the harmonica was his first instrument.
Lennon’s first instrument was actually the banjo, which he learned to play as a teenager. He later transitioned to playing the guitar and became proficient on that instrument as well. The harmonica was one of the many instruments he added to his repertoire, but it seems it was not the first one he learned.
