Zhang style singing and its accompaniment music are an artistic whole. Mr. Zhang Junqiu has collaborated with Beijing erhu performer He Shunxin for more than 50 years, and has also collaborated with Beijing erhu performer Zhang Siyun for nearly 50 years. Their joint creation over the past thirty years is also an example of a perfect combination in the history of Peking Opera music. He Shunxin and Zhang Siyun not only gave Zhang Junqiu great assistance and help in accompaniment, but also made unique contributions in the creation of accompaniment tunes including "Guomen" and "Headover". To learn Zhang style singing, one must also learn the accompaniment music of He Shunxin and Zhang Siyun and their original playing techniques.
