Directed by Nikolai Sokoloff, former principal conductor of the Cleveland Orchestra, the Federal Music Project employed over 16,000 musicians at its peak. Its purpose was to create jobs for unemployed musicians, It established new ensembles such as chamber groups, orchestras, choral units, opera units, concert bands, military bands, dance bands, and theater orchestras. They gave 131,000 performances and programs to 92 million people each week. The Federal Music Project performed plays and dances, as well as radio dramas. In addition, the Federal Music Project gave music classes to an estimated 132,000 children and adults every week, recorded folk music, served as copyists, arrangers, and librarians to expand the availability of music, and experimented in music therapy. Sokoloff stated, "Music can serve no useful purpose unless it is heard, but these totals on the listeners' side are more eloquent than statistics as they show that in this country there is a great hunger and eagerness for music."
