Judson had a naturally high voice, a pure tenor. My voice was a baritone, though I sang falsetto easily, and Asa had a deep bass. Abby had an old-fashioned "counter" or contralto voice. The result was an effect like that of a male quartet. Abby's part being the first tenor, Judson's second tenor, mine first and Asa's second bass, respectively. But we practiced an interchange of parts as we sang, and the blending of the voices was so perfect that it seemed quite impossible for the audience to distinguish the several parts.
