The choir is one of the most distinctive symbols of Latvian musical culture. Choral culture encompasses not only concerts but also music education, rehearsals, the work of conductors, the preparation of compositions and arrangements, competitions, and the learning of repertoire for the Song Festival.
A mixed choir is usually divided into soprano, alto, tenor, and bass sections. Each performs its own part, which means that several melodic lines sound simultaneously. One may carry the main melody, while others support the harmony, create rhythmic movement, or provide contrast. This simultaneous sounding of several independent voices is called polyphony.
A choir singer must enter precisely, maintain accurate intonation and rhythm, pronounce the text clearly, and listen to the other singers. A choir therefore develops not only the voice but also the ability to cooperate: the collective result depends on every participant. A special form of choral performance is a cappella singing, in which the voices are not accompanied by instruments. The choir must then sustain the harmony and musical tension on its own, while the listener can clearly hear the colours of the voices, the harmonies, and the words.
At the Song Festival, choral singing acquires a broader social significance. Choirs from different regions of Latvia and Latvian communities abroad learn the same repertoire. The nationwide Song Festivals, held since 1873, transformed the choir into one of the most important public expressions of Latvian musical identity: thousands of individual voices merge into one collective sound.
