Trenton children beginning music study will have their own instruments to take home for practicing, and neglected instruments will find a whole new life, as Princeton University’s Office of Public Affairs and WWFM The Classical Network host “Instruments of Change,” benefitting the Trenton Community Music School. From November 30 through December 4, the Office of Public Affairs will open its doors for members of the community whose musical instruments are in need of a good home. Families whose children have outgrown their small instruments, shifted their interests away from playing, or developed into the need for a finer instrument, will find grateful recipients for their ½-size violins, novice-level flutes, or instruments that are no longer played. The Office of Public Affairs is located at 22 Chambers Street in Princeton, and will be open for donations from 9 a.m. to 5 p.m.
