NOTES OF A JOURNEY ON
Note on the a Kan.a
The Kan, the reed-organ used so much among the northern Lao tribes, is remarkable for the sweetness of its tones, and the fact that the intervals of the notes are correct according to our f t musical ideas, and have a true key-note, the pitch of the instrument depending on its length.
Thus the five-sok kan (9 feet 4 inches long) is in the key of Graone sharp.
The four-sok kan (6 feet 8 inches) in the key of Da two sharps.
The two-sok kan (3 feet 4 inches) in the key of Fa one flat.
These are the lengths most usual, but six soks is sometimes used; it possesses very fine low tones, but requires powerful lungs, although the notes are produced by inspiration and respiration.
The number of reeds never exceeds fourteen, and the arrangement of notes is as follows, numbering the reeds in couples from the mouth of the little air-chamber :aThe two reeds, 1, are played with the thumb; left 1 being the key-note; right 2 being the lower octave of the same. The octave thus goes from right 2, to 3, 4, 5 and 6 left (or right 3, which is the same) on to right 4, 5, and back to the thumb note on left 1.
Below the key-note right 2 come left 2 and right 1, and above the upper key-note, right 6 and 7 and left 7; thus, in the D kan of four soks, we geta
FOUR-SOK KAN (1 INCH TO 2 FEET).
TWO-SOK KAN.TWO-SOK KAN.
