didnt know Barbershop music was a category of music.
Oh yes, it's a vocal harmony codified during the barbershop revival era. It's mostly a cappella
oh ok, seems kind of a dead art tho.
Oh, yes, it is a dying breed. But when it was in full swing it was mostly played by a barbershop quartet, a group of four singers.
Oh so barbershop quartets that makes sense, thought it was more inline of something like elevator music but it means quartets
Oh, yes the quartets usually have a lead, a bass, a tenor, and a baritone. They all harmonize together to entertain barber patrons.
