The music festival started very late in China, but has a history of more than 40 years abroad. For those well-known foreign music festivals with decades of history, music performances are no longer their entire content. Whether a music festival is successful or not, in addition to wonderful music performances, whether there is good interaction between the music festival and the audience has become another criterion. Looking at first-class foreign music festivals, public welfare themes combined with rich audience experience services are the best interpretation of the interactivity of music festivals. As a new music festival, Rebo Music Festival also emphasizes interaction with the audience. It is based on the unique background of Chengdu and draws on successful foreign experiences to create the most interactive music festival in Chinese history.

In 1949, UNESCO created a music organization called the "International Music Commission", with its offices in Paris. More than 50 countries around the world sent representatives to participate in this committee. The International Music Committee often organizes some international music conferences, holds various types of international music competitions, and sponsors some young musicians to hold international tours. In 1979, at the 18th Congress of the International Music Committee held in Australia, an agenda was adopted, setting October 1 as "International Music Day" starting in 1980. International Music Day is a day for international music and cultural exchanges between musicians from all over the world. Many countries in the world hold music and cultural exchange activities and perform various music performances. The International Music Committee issues awards every two years on "International Music Day" to reward musicians who have made significant contributions in music creation, performance, music education, etc.
