what musical percussion family instrument called zils was used with singing slogans?
Tambourine The tambourine is a musical instrument in the percussion family consisting of a frame, often of wood or plastic, with pairs of small metal jingles, called "zils". Classically the term tambourine denotes an instrument with a drumhead, though some variants may not have a head at all. Tambourines are often used with regular percussion sets. They can be mounted, for example on a stand as part of a drum kit (and played with drum sticks), or they can be held in the hands and played by tapping or hitting the instrument.
Bongo drum Bongos (Spanish: "bongó") are an Afro-Cuban percussion instrument consisting of a pair of small open bottomed drums of different sizes. In Spanish the larger drum is called the "hembra" (female) and the smaller the "macho" (male). Together with the conga or tumbadora, and to a lesser extent the batá drum, bongos are the most widespread Cuban hand drums, being commonly played in genres such as Cuban son, salsa and Afro-Cuban jazz.
