CHOIR IS A SINGER STAFF

 Choir class group of first-year students Muz-10, Faculty of Design and Art Choir singing group - a musical ensemble consisting of singers (chorists, choir artists); joint sounding of human voices.
 A choir differs from a vocal ensemble (vocal trio, quartet, quintet, etc.) by the presence of at least two (according to P. Chesnokov, three) or more people performing the same part.
 The choir is led by a conductor or choirmaster. The leader of the church choir is called the choir. Most often the choir includes four choral parts: soprano, alto, tenor, bass. But the number of parties is in principle not limited, since each of these main parties can be divided into several relatively independent parties (this phenomenon is called divisions among musicians.
 
 The choir can sing with or without instruments. Singing unaccompanied is called a cappella singing. Instrumental accompaniment can include almost any instrument, one or more, or an entire orchestra.
 
 As a rule, at rehearsals of the choir, in the process of learning a piece written for a choir and orchestra, the orchestra is temporarily replaced by a piano; the piano is also used as an auxiliary instrument in the practice of a cappella choral pieces.
