one particular type of drum. A master drum can be an atsimevu, sogo, kroboto, totodzi, or an agboba; these are the only types of drums used as master drums, however. Different master drums are used in different pieces. For example, if a group is playing "Agbadza" (an old Ewe war dance), the master drummer plays the sogo. The master drum techniques and playing styles are generally the same regardless of which drum is used. Sogo The basic master drum is called a sogo (pronounced "so-go)". Sogo is the drum that can always be a substitute for the master drum. It is also the actual "correct" master drum for some pieces. The sogo is a larger version of the kidi and is taller and fatter than the kidi. It can be played either with two wooden sticks, one hand and one stick, or both hands. This depends on the technique used in the piece being played. Depending on the piece, sometimes the sogo can play the same support role as the kidi. It produces a low tone and is usually played sitting down or standing up. Atsimevu Another master drum is called atsimevu (pronounced ah-chee-meh-voo). The atsimevu is the tallest of the Ewe drums. It is around 4½ feet tall. To play the atsimevu, the drummer must lean it over a stand called a vudetsi, stand on one side of the drum—and play it with either two wooden sticks or one hand and one stick. The atsimevu makes a middle range sound with some bass in the sound. In the understanding of a drummer, a drumming stick is an extension of the hand. It remains under constant control in order to release only the desired frequency of vibration as it strikes the membrane. There are four types of stick drumming techniques in the art of master drumming, a basic technique and three variants of this technique. Each of these techniques produces a distinct pitch of the Atsimevu pitch series. . . In terms of a performance technique, the duration of resonance of a tone is normally controlled by damping the membrane at the periphery with a light but firm touch of the weak hand fingers. This technique is of prime importance in the articulation of the structure of a drum music or vugbe. It provides the means of indicating the basic motives, phrases and periods out of which the drum music
