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.
Hsaing waing The hsaing waing (Burmese: ဆိုင်းဝိုင်း , ] ; also spelt saing waing) is a traditional Burmese folk musical ensemble, consisting of a number of different gongs and drums, as well as other instruments, depending on the nature of the performance. These include the "hne" (a double reed pipe), "pat waing" (a set of 21 drums in a circle), "kyi waing" (small bronze gongs in a circular frame), "maung hsaing" (larger bronze gongs in a rectangular frame), as well as "chauk lon pat" (a set of 8 tuned drums), and "si" and "wa" (bell and clapper). For more formal and classical performances, the ensemble may be accompanied by the "saung gauk", the Burmese harp, the "pattala", a Burmese xylophone, or the piano and violin, both introduced during colonial rule. "Hsaing waing" musicians use a hemitonic and anhemitonic scale similar to the one used by Indonesian gamelan musicians.
