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.
Rhoptron A rhoptron (ρόπτρον, plural: rhoptra) was a special buzzing drum used in Ancient Greece associated with the Corybantes. According to Plutarch, it made a frightening sound, resembling a mix of animal noises and lightning, and was used by the Parthians to scare their opponents in battle instead of the more typical Greek battlefield instruments, the salpinx or horn.
