Music is brought to the children as another language that they can grow to understand and love. Through singing together, they begin to place themselves with others in society. Beginning in first grade, children sing and play pentatonic flutes. This helps them develop the art of listening while exploring rhythm, words and melody. As they progress through the grades, children move from songs in unison to the beginning of harmony work (the singing of rounds) and the playing of more complex instruments, such as diatonic flutes and violin. With their musical comprehension and skills building from year to year, children can read music, play in ensemble and sing in directed choral groups by the time they reach sixth, seventh and eighth grades.
