A musical wind instrument of the open tube type such as a saxophone is disclosed herein and includes a hollow body portion having an upstream upper part and a downstream relatively lower part, each part being provided with a plurality of upper and lower tone holes respectively. An upper tone changing sub-assembly, disengageably mounted to the upper part of said body portion includes a plurality of keys and key-cups which are conventionally operated by the fingers of the left hand for opening and closing individual ones or various combinations of the upper tone holes to vary thereby the tonal qualities of the instrument. In like manner, a lower tone changing sub-assembly is disengageably mounted to the lower part of said body portion and includes similar components which are conventionally operated by the fingers of the right hand for opening and closing the lower tone holes.
