Chinese musician Winnie Wong shows how the guzheng or Chinese zither has developed from a simple folk instrument, into the concert instrument of today. From the mid 19th century, the guzheng has gradually developed as a solo instrument. Players have introduced new performance techniques such as using the left hand as accompaniment to the right hand melody, bending and vibrato.
After watching the clip, ask the students what the instrument is made out of. Ask them how it is different to another stringed instrument such as a guitar. Introduce the idea of a pentatonic (5 note) scale. Ask students to compose a melody based on a pentatonic scale.
