Each class is 45 minutes long, and semesters run for 8 to 12 weeks depending on the time of year. The lessons are a series of brief, age-appropriate activities involving music or rhythm that benefit the children in all areas of their development. Specific activity benefits are shared periodically to give caregivers insight into their child’s developmental needs. Singing, moving to music, chanting, object exploration, rhythm instruments and story-time are regular segments of each lesson.
