The fundamental characteristic of Shen Yun Performing Arts vocal soloists, is their use of bel canto vocal technique while singing Chinese lyrics. This means that the singer must grasp the highly difficult technical requirements of bel canto operatic singing while retaining the proper Chinese articulation and diction—today, this is unparalleled. The lyrics are all original compositions. Brimming with philosophical reflection about human life and deep layers of meaning, they traverse the boundaries of nation, race, and culture and have been fondly received and appreciated the world over. Some audience members even call Shen Yun’s songs "hymns."
