These various forms of music have their respective instruments, which, though few in number, differ considerably one from the other. The first is the _raïta_: in shape it resembles a short trumpet bored with holes, on which rest the fingers, and with a bell-shaped mouth. The sound is created by vast quantities of air being blown through a reed mouthpiece, producing a sound not unlike the bagpipes, only much louder. In fact, I have rarely heard one man produce such an ear-piercing and strident squeal as the _raïta_-player, and sitting close up to the music is pain and grief. This instrument is used exclusively for dancing, and it is accompanied by a man with a _tam-tam_ or a _derbouca_. The _tam-tam_ resembles in shape a very large tambourine, and is played with both hands, producing a rather dry, rhythmical cadence. The _derbouca_ looks like a large flower-vase with a round body and a long neck. Over the farther end is stretched a piece of skin, and the playing is the same as the _tam-tam_, but with a much deeper sound. In addition to the above, one often sees a tambourinist; but the usual orchestra for dancing consists of two men—the _raïta_-player and the drummer, with his _tam-tam_ or _derbouca_. The second type of wind instrument is the flute. This is either the ordinary penny whistle made out of a reed and producing the same sort of music, only softer, or the long flute, chiefly found in the southern areas. The flute is the most interesting of all the Arab instruments and the hardest to play. It consists of a long reed hollowed out, about half an inch in diameter and from two to three feet long. It has eight stops, but there is no sort of mouthpiece. The sound is produced by the player blowing across the top of the flute at some particular angle which I have never been able to discover, and producing the softest, saddest, deepest note one can possibly imagine. To the most unmusical the sound of the long flute must appeal, and when accompanying one of those love ballads of the far South it is enchanting. These two flutes are used to accompany all kinds of songs, but chiefly those concerning the exploits of heroes and the love lays which hold such a big place in all Arab melodies. Occasionally it is used to follow religious chants, but not always. The flute is usually accompanied by the _tam-tam_ or the _derbouca_, which is played very softly. Moreover, the accompaniment to the song is more often only heard between each verse, while during the singing it is just a faint drone with a distinct time-beating, and sometimes no music at all.
