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.
Trikiti The trikiti (standard Basque, pronounced ] ), trikitixa (dialectal Basque, pronounced ] ) or eskusoinu txiki ("little hand-sound") is a two-row Basque diatonic button accordion with right-hand rows keyed a fifth apart and twelve unisonoric bass buttons. The onomatopoeia "trikiti", apparently stemming from the sound emitted by the tambourine, originally referred to a traditional Basque ensemble, made up of the instrument which now bears the name as well as alboka, txistu and other instruments.
