The Chanter produces the melody. It consists of a hollow cylindrical tube, about 24 cm in length, into which holes are drilled to produce individual notes. The bottom end is permanently closed and a double beating reed is mounted at the bag end. The reed is encased in a chanter stock which is tied into the bag. The most common chanter is one consisting of eight finger holes (one complete octave) and 7-keys. The 7 keys extend the chanter down below the bottom tonic note by 3 notes and 2 notes above the top tonic note, with the remaining two keys producing sharps. Chanters can be made with extra keys; 9, 11, and 17 are the most frequently produced combinations with the 17-keyed chanter producing a chromatic two-octave range.
The commonly used F-chanter is so-called because the finger holes produce the scale of F-Major. For such a set of pipes, music is normally written in the keys of G, D, A-major, E, and A-minor. In all cases, each of the keys mentioned is transposed down one whole tone. In musical terminology, the pipes are a B-flat instrument. Chanters of different pitches can be produced namely; C, D, and G-chanters, which are commonly seen and heard. They are so-called because the notes produced by the finger holes produce the respective scales of C, D, and G-major. To accommodate the change in pitch the drones are likewise adjusted in length to produce the appropriate harmony. The overall effect is that the pipes can be played in an impressive range of musical keys.
