Nassau Senior Treble Choir – The Metropolitan Youth Orchestra of New York


The Nassau Senior Treble Choir, led by Music Director Louise O’Hanlon, is a four-part women’s ensemble for high school vocalists. Members are exposed to classical, contemporary, and multicultural music with the goal of fostering an understanding of world cultures. Singing is an intensely personal experience, and it is our hope that by making a deep connection with the music, members will, in turn, learn something about themselves and the world at large. As the Senior Treble Choir comes together to form a community of singers, we can, in turn, form a community of young people who care about each other and who spread joy through their music-making.
