Walden School held its annual Winter Sing concert last Thursday evening. Students in grades 4-6 performed instrumental as well as choral pieces in two performances to capacity crowds in the Toby Hayward Community Room. This year’s theme was Broadway musicals and included music from Hamilton and Phantom of the Opera. Students played a wide variety of instruments, including piano, guitar, xylophone, metallophone, violin, viola, flute, oboe, bass-guitar and drums. Before the show, 2nd- and 3rd-graders held a bake sale to benefit Tree People. The entire Walden community came together to share a musical experience and support the Upper Core students after weeks of hard work.
