Ngan Khoi Chorus, a Southern California based not-for-profit organization, was established in April, 1989 for the purpose of promoting choral singing among Vietnamese Americans. Ngan Khoi believes that choral singing nurtures both spiritual growth and social responsibility. Using one's own voice as an instrument, a singer gains a profound sensation caused by the vibration of the vocal chords and the physiological impact of the sound. In the choral environment, a singer interacts with others to achieve a state of perfect sensation by the sheer synchronization of vocal sounds. Choral singing leads to a balanced sensitivity, which contributes to harmonious living.

Ngan Khoi Chorus has been on the forefront of producing and promoting the appreciation of folk and classical music in the Vietnamese American community in an effort to bring about a consonant blend of Vietnamese and American music traditions. This way, the music speaks as an ambassador acting as a cultural bridge between Vietnamese and American people.
