"I have been longing to create innovative pieces in pop opera by taking inspiration from classical masterpieces," Cai, 25, says.

Last month, he released a new single in the subgenre, titled Amore Mio, Dormi Bene, which draws inspiration from Schubert's Lullaby. The inspired song has two versions, one in Chinese and the other in Italian.

"The Chinese version features an instrumental arrangement with a regretful tone and incorporates pop music elements into the chorus for a more contemporary interpretation. The Italian version, on the other hand, embraces a classical style and expresses a sense of nostalgia," he explains.

The song has a vocal range spanning nearly two octaves, and Cai's vocal prowess is on full display, as he navigates both lower and upper registers with ease.

Producer Liu Huyi enriches the single's conventional classical music arrangements with the piano, strings and harp. He incorporates electronic elements into the mix, seamlessly fusing classical style and contemporary pop elements.

In Cai's quest to pursue the "popopera style", he has dedicated years to exploring new possibilities and pushing the boundaries of his craft.

"I want to incorporate a blend of musical genres, including electronic, rock and traditional Chinese folk music into my songs," he says, adding that he has contemplated collaborating with suona players, who are skilled in playing the double-reed woodwind instrument, for his live performances.

By embracing a diverse range of musical influences, he believes that he can connect with a broader audience, particularly among the youth, and create music that transcends cultural boundaries.
