A guzheng's strings are made from steel with nylon wound around it. Formly made from spun silk. The number of strings can be anywhere from 6 to 23. A guzheng with 21 strings is the most common. The more strings, the higher the octaves of the instrument, i. e. 16 string has 3 octaves, 21 string has 4 octaves.
