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.
Zamina mina (Zangalewa) "Zamina mina (Zangaléwa)" is a 1986 hit song, originally sung by a makossa group from Cameroon originally named Golden Sounds, popular in Africa for their use of dance and costumes. Due to the song's popularity, the group renamed to "Zangaléwa" during its mainstream success. Zangaléwa pays tribute to African skirmishers (a.k.a. tirailleurs) during World War II. Most of the band members were in the Cameroonian Army themselves, and used the song in fund-raising efforts for Comic Relief.
