What would be better for a simple little program inside the class in a dormitory?

Chorus.

Chorus (hé chàng; chorus) refers to the collective singing of multi-part vocal works of art, often with a conductor, can be accompanied or unaccompanied. It requires a high degree of unity of a single voice and melodic harmony between voices, and is one of the most popular and widely participated forms of music performance.

Chinese choral art can be said to be the youngest family in the musical territory. Mr. Huang Zi's oratorio "The Song of Long Hate," written in 1933, is one of the earliest large-scale choral works.

Composer Xian Xinghai's "Yellow River Cantata" quickly spread throughout China after its premiere in Yan'an. After the founding of New China, the choral cause flourished, many professional choral groups were established, and amateur choral singing was also very active.

In 1958, Xiao Bai, Wang Jiufang, Wang Qiang and Zhang Yingmin of the Shanghai Conservatory of Music composed the "Happy River Chorus", which won the first prize in the music competition of the Seventh World Youth Festival, and the "Long March Song", which came out in the early 1960s, had a clear theme and a novel form, and was well received by the general public.

Qu Xixian and other composers adapted the folk songs "Half Moon Climbing Up", "Pastoral", "Alamu Khan", "Ussuri Boat Song", "guests from afar, please stay" and so on, have become our country's choral classics, loved by the people, and at the same time, there are also a large number of choral songs and suites.
