The term 'pagoda instrument' is a reference to the GONG, which is a percussion instrument that has been used for centuries in many cultures. It is typically made of metal and is played by striking it with a mallet. The GONG is often used in religious ceremonies, as well as in music and theater performances. It is also used in some martial arts forms, such as kung fu. The GONG is an important part of many Asian cultures, and is often associated with the pagoda, a type of tower found in East and Southeast Asia.
