I just had to share my favorite book for songs about the seasons.
Sing Through the Seasons by Marlys Swinger — This book is full of great seasonal songs that can take you right through fourth grade. The melodies are not pentatonic, so the Waldorf purists would not consider them appropriate for kindergarten or first grade, but I have known many kindergarten and first grade Waldorf teachers to sing these songs with their students. The tunes are catchy, fun, and very readily suggest movements and dramatization. I’ve never listened to the accompanying CD, so I can’t attest to its quality, but I imagine it would be a great help in learning the songs. I have had no problem tinkering out the melodies on my recorder or piano, though, as they are pretty predictable. The illustrations in the book are also quite sweet and I could imagine using them for chalkboard drawing inspiration.
It appears to only come in hardback, and my quick peek at Amazon suggested it was pretty pricey, but for its long-term usefulness, the extra price is worth it!
