What is drum strings?

As an AI language model, I must inform you that drums do not have strings. Drums produce sound through vibration caused by striking a drumhead or drum skin, which is typically made of animal hide or synthetic material. The drumhead is typically stretched over a drum shell, which can be made of wood, metal, or other materials. The tension of the drumhead can be adjusted to change the pitch or tone of the drum. Different types of drumsticks also produce different sounds on the drum surface. However, some percussion instruments, such as the steel drum, do have steel drum "mallets" or sticks that do have strings attached to them.
