Interactive singing may become increasingly audience oriented in the future, but live singing remains a prerequisite for interactive singing. The performance market in 2023 is booming, with many cities being "contracted" for concerts on weekends. The concert was full of flowers, and the fans did not follow the routine and created many new "gameplay". For example, 'There is no need to sing in person for a concert, fans sing to idols.'. Recently, singer Wu Bai frequently made headlines due to his fans' "singing on his behalf", which has led to numerous "memes" created by netizens. Even though he responded, 'This is not the truth, I sang', it seems that no one cares except for him - after all, the singing from the live audience still lingers after the concert is over. Netizens joked that Wu Bai himself doesn't seem to have to appear. As long as he packages the venue and releases the performance date, fans can successfully hold a "Wu Bai Concert Without Wu Bai". Expressing love and support for the singer through enthusiastic choirs is becoming increasingly fierce. In this year's MY TREE OF LIVE world tour by Miriam Yeung, both the lead songs such as "Unfortunately, I Am Aquarius" and "Big Things in a Small City", as well as non lead songs such as "River Boy" and "Fireworks", can trigger a chorus; At Mao Buyi's "Young Bird Guide" national tour concert, old and new songs such as "Ordinary Day", "Midsummer", and "City Evening" all received a full chorus. From singing along to singing in chorus, the interaction between the audience and performers is becoming stronger and stronger. In addition, writing words to the singer on the banner, creating a "starry sea", and performing a song together with the singer have also become highly accepted "concert ceremonies". In 2023, everyone will not only "watch concerts", but also "participate in concerts" in a deeper and more interactive way. From listening to music to singing, the keywords are "expression" and "resonance". Li Meng, a girl born in the 1990s, works in an internet company and has been listening to concerts since her third year. At first, she liked to sit quietly in her seat and listen, "It was my first time attending a concert and seeing my favorite singer with my own eyes, so I didn't want the singer's voice to be disturbed, even my own. Now she prefers to participate in the choir, "it gives me a sense of participation, freely experiencing joy between singing and jumping. During the National Day holiday, bank employee Zhou Zhou and friends went to watch a concert. My seat is next to the ticket area, where most of the audience is not enthusiastic and there is no choir sitting quietly. "She said that the entire concert was very quiet, resulting in a bad impression. However, Zhou Zhou understood this behavior: "Everyone has different feelings and expressions, and whether to sing or not is a personal choice." Regarding singing, Liu Jiayue bluntly expressed her disapproval. At one concert, the audience next to her sang all night, with a loud and out of tune voice. Liu Jiayue sighed, "I didn't hear the singer's voice at all, I feel like I bought the ticket for nothing." Ding Zigao, the producer of the MY TREE OF LIVE World Tour and founder of Zhengzheng Culture and Entertainment Co., Ltd., believes that in the atmosphere of pop music culture, audience interaction with the singer is a common phenomenon. Many popular music creations originate from everyday life and are prone to resonate, leading to the emergence of choruses and
