New York Symphony Orchestra. The tour included 26 concerts in major cities of Europe. Originally a three-year program, the Choir School moved to Ithaca College in New York State in 1929 and enlarged its curriculum to a four-year program culminating in a Bachelor of Music degree. A major reason for the move involved the need to be able to reach the major cities of Chicago, Philadelphia, and New York by rail. All three were cities that sought the choir under Williamson. 1932–1991: Independent music school in Princeton In 1932, the choir school relocated to Princeton, New Jersey, which became its long-term home. Classes were held in the First Presbyterian Church and the Princeton Seminary until 1934, when the school moved to its present campus. This was made possible by a large gift from the Ohio philanthropist Sophia Strong Taylor. The dedication of the new campus was marked by a performance of Johann Sebastian Bach's Mass in B minor at the Princeton University Chapel with the Westminster Choir, soloists, and the Philadelphia Orchestra conducted by Leopold Stokowski. The services of the soloists, orchestra, and conductor were a gift from Stokowski. There was a second European choir tour in 1934 lasting nine weeks and highlighted by a live radio broadcast from Russia to the United States. In the 14 years since its founding in 1920, the choir already had two European tours, which earned it international acclaim and a campus of its own. The State of New Jersey in 1939 granted the choir school accreditation and the name Westminster Choir College was adopted. In years to come, under Williamson's leadership, the choir would begin having regular concerts with the New York Philharmonic and the Philadelphia Orchestra. The Westminster Choir sang with the New York Philharmonic for the first time in 1939, conducted by Sir John Barbirolli. Since that time, the choir has sung over three hundred performances with the Philharmonic, a record number for a single choir to perform with an orchestra. Later that year, the choir sang with the NBC Symphony Orchestra, conducted by Arturo Toscanini. That same year the choir, directed by Williamson, sang at the dedication of the New York World's Fair, which was broadcast to 53 countries. In 1957, under the auspices of the U.S. State Department Cultural Exchange Program, the choir undertook a five-month world tour, concertizing in 22 countries, covering and appearing before approximately a quarter-million
