  • Chromatic wind instrument
    Patent number: 6891096
    Abstract: A wind instrument comprising a plurality of pipes each having a respective open. The instrument also comprises a plurality of movable elements each configured to move in relation to a corresponding one of the plurality of pipes and defining a respective movable end of the corresponding one of the plurality of pipes.
