Just as humming a merry tune helped Snow White and her furry animal friends to quickly clean a filthy cottage in the movie "Snow White and the Seven Dwarfs" (Disney & Cottrell, 1937), singing can be an effective way to help keep young children fully engaged during classroom transitions. The purposes of this article are to: (1) consider why classroom transitions are often challenging for young children and teachers; (2) review findings that support the idea of singing as a catalyst for easing transitions in the early childhood classroom; (3) examine the benefits one teacher experienced when she incorporated singing into two of her classroom transitions; and (4) suggest ways early childhood teachers can appropriately use singing as a classroom management technique.
