The Origin of “Bass”
The musical term bass comes from the Medieval Latin word bassus, meaning low or short. It entered English through Italian and other European musical traditions, where it described the lowest musical part in a composition.
The fish name bass, however, has a different origin. It comes from an older Germanic word referring to a type of perch-like fish.
Because these words evolved separately, English kept both spellings even though one pronunciation matches base.
