What is the name of the ancient musical instruments often used in religious ceremonies by followers of Isis?

The sistrum is recognized as a percussion instrument that was notably used in the worship and religious ceremonies dedicated to the goddess Isis in ancient Egypt. Its distinctive rattle, produced by rods that move freely within a U-shaped frame, made it an important component of the ceremonial music that accompanied various rituals. The sistrum was believed to evoke the goddess’s presence, facilitate communication with the divine, and was often used to enhance the spiritual atmosphere during worship.

In contrast, the other instruments listed have different cultural associations and purposes. The aulos, a double-reeded woodwind instrument, was more commonly utilized in Greek music and often in theatrical settings. The kithara, a type of string instrument, was also associated with Greek music and was used for various musical performances, including those in honor of gods but not specifically tied to Isis. Lastly, the lyre, another stringed instrument, was frequently used in both Greek and Roman contexts, but like the kithara, it was not particularly connected to the worship of Isis. This sets the sistrum apart as the instrument uniquely identified with the religious practices surrounding Isis.
