The earliest musical society in Worcester, of which any reliable record is to be found, was the Worcester Harmonic Society. The exact date of its formation cannot now be ascertained, but it was in existence as early as 1825, at which time Emory PERRY was president and Henry W. MILLER was secretary; and in October 1826 the society gave an oratorio at the Old South Church. This society also furnished the musci to the Fourth of July celebration in the last named year, on which occasion Hon. Charles ALLEN delivered an oration. The society continued in existence for several years, occasionally giving concerts and often furnishing the music on public occasions.( In 1815, there was a musical society in the county called " Old Hundred Musical Society", wich gave a cncert in Hopkinton, MA that year, and itis quite probable that some of the Worcester musicians and singers were members of it." In 1845 the Worcester Sacred Misical Society was formed, wit Rufus D. DUNBAR as presidet, and the next year gave a miscellaneous concert in Brinley (now Grand Army) Hall and mention is made in the newspapers of a concert given in the Spring of the following year. It is probable tat this society was in existence only 2 or 3 years. In September 1850, the Worcester Mozart Society, the first regularly organized association fr musical culture was formed, with Putnam W. TAFT as president and Albert L. BENCHLEY vice president. This society continued in active existence till November 1866, when it was united with Beethoven Society, formed in 1864 with Austin L. ROGERS as president. The nae after the union was the Worcester Mozart and Beethoven Choral Union, the first president being Edward HAMILTON, William SUMNER as vice president, and Carl ZERRAHN as conductor. The society was incorporated in 1872, by a special act of the Legislature, as the Worcester Choral Union and I.N. METCALF was chosen prsident, J.A.TITUS was vice president and B.D.ALLEN conductor.
