For Sean And Lyla Lo … Practice Does Make Perfect - 5:56 am Sean and Lyla Lo are fulfilling personal pledge to never miss a single day of piano practice. Courtesy photo MUSIC News: Two young piano students in Los Alamos — brother and sister Sean Lo, 11, and his sister Lyla Lo, 9, — are making great advancement and earning well-deserved awards in their chosen study of classical piano by fulfilling a personal pledge to never miss a single day of practicing. Both students take part in a national “challenge” to continually practice the piano without ever missing a single day of practice. At the suggestion of their parents Hanju Tsai and Chienchi Lo, as well as their teacher, Dr. Madeline Williamson, both students enrolled in the national program shortly after beginning their formal piano study. Sean has just completed practicing piano 1,189 consecutive days and his sister Lyla has accomplished 1,059 of uninterrupted days of practice.
