In Tibet, then, the folk-tunes are simple, short, and emphatically not such “good tunes” as the airs of Nepal. But, in addition to the songs of the peasants and beggars, there is the more highly-organised and orchestrated music of the monasteries. This is usually played with three groups of instruments—first and foremost the percussion; drums of all sizes from those made of a human skull to others 3 and 4 feet in diameter, and cymbals of great resonance and good tone, coming often from China. The cymbals are taken very seriously, and each different way of clashing them has a special name and a special religious significance. The hard-worked percussion department keeps up a continuous rhythm throughout the performance of a devil-dance or other musical festival; and to its strenuous and often sinister efforts are added from time to time the sounds of the two groups of wind instruments. The first of these, playing airs which often possess great charm, are the double-reed oboes, about twice as long as our European oboe, and very often provided with equidistant holes, rendering them incapable of playing save in the scale of whole tones (or a close approximation to it). The second and larger wind instrument is the long straight trumpet, 8 to 12 feet long, of which the fundamental note is almost continuously blown. Most monasteries have two of these, about one tone apart in pitch; but as the longer of the two is blown so as to play its first overtone, while the fundamental note is played on the other, a drone bass of a minor seventh is the resulting sound. This adds to the sinister impressiveness of the music, and provides an effective accompaniment to the quaint tunes of the oboe-like instruments. At a devil-dance performance, the orchestra plays for a whole day, or perhaps two, almost without rest either for itself or for its listeners. In addition to these instruments, a fairly civilised violin is used in Tibet, especially by wandering beggar minstrels. This is about two-thirds as long as our violin, and has four strings, tuned A,D,A,D, in that order. The bow has two hanks of hair, one of which passes between the first and second strings, while the other goes between the third and fourth. Thus, by pressing the bow in one direction the two A strings are sounded, producing a reinforced note (i.e. two notes in unison); by pressing the bow in the other direction the sound of the D strings is obtained. The strings converge towards the top of the instrument, so that they can all be fingered at once. The Tibetans become very agile with their fingers, and I have heard very skilful performances of rapid, jolly dance-tunes by wandering minstrels; these tunes, like the songs of the peasants, are usually in the pentatonic scale. One more instrument must be mentioned—the trumpet made from a human thigh-bone. This is not very commonly used in the larger monasteries, but occasionally sounds a note in the ritual of the worship of smaller villages.
