An adjustable chanter for mounting in an outlet tube of a set of bagpipes includes a conventional reed and a conventional chanter pipe having a series of finger holes by which notes can be selected. The chanter pipe has a collar at an upper end which is screw fastened to a hub defining a sleeve arranged which extends from the upper end of the chanter pipe into the tube of the set of bagpipes as a friction fit within the tube such that the hub is supported in the tube for receiving air through the tube from the bag for passing through the pipe for playing the notes. The position of the mouth of the reed relative to the holes in the chanter pipe is adjusted by a shuttle which slides longitudinally in the hub moved by a manually operable shaft projecting from the hub to one side and manually rotatable so that the reed can be adjusted to change tuning without rotating the chanter pipe or removing the chanter pipe from the tube of the bag.
