Xalam - Construction and Tuning

Construction and Tuning

The xalam, in its standard form, is a simple lute chordophone with one to five strings. The wooden body (soundbox) membranophone of the instrument is oval-shaped and covered with the hide of cattle. The strings of the xalam are typically made of two or three tightly wound strands of low-gauge nylon fishing line; these strings are fixed to the instrument's wooden neck by long and narrow leather strips and to its wooden bridge by cotton strings. By moving these strips, the instrument's tune can be adjusted. The xalam usually has two main melody strings that are fingered by the left hand (like the strings of a guitar or banjo) and two to three supplementary strings of fixed pitch. Most xalam players construct their own xalams, although they usually call on woodworkers (lawbe) to carve the body, neck, and bridge for them.

In most Wolof-speaking parts of Senegal, the xalam has three principal tunings, all of which involve tuning the two main strings a perfect fourth apart. In the first tuning (ci suuf or low), the main strings are tuned 1 and 4 ( 1 being the fundamental of a major scale), with three supplementary strings being tuned an octave higher to 1´, 2´, and 3´. The second tuning (ci kow or high) uses the same string intervals but the fundamental is placed a minor second above the higher melody string, meaning that the open main strings now play the role of 3 and 6, with the supplementary strings acting as 3´ and 4#, the highest supplementary string usually being ignored. In the third tuning (ardin), the fundamental is a minor third above the lowest main string and the main strings are tuned 6 and 2, with supplementary strings tuned to 5 and 1´. The third supplementary string is either ignored or is tuned to 6 or 2´. If playing in an ensemble, the ardin xalam's main strings are tuned a minor third below the cu suuf xalam, and the ci kow xalam is tuned a major third above the ci suuf xalam to ensure that the fundamentals of each xalam coincide. (Thus, if the ci suuf xalam's lowest note were C, the ardin’s lowest note would be a low A and the ci kow xalam’s lowest note would be E.)
