The Building Blocks series offers an alternative to traditional notation by using color-coded squares and rectangles introducing left to right reading, vertical relationships of pitch, and horizontal relationships of duration. Volume 1 is a collection of detachable song charts that includes 12 familiar children's songs: "London Bridge," "Rain Rain," "Twinkle Twinkle Little Star," "Mary Had a Little Lamb," "Bounce High Bounce Low," and more. Song charts may be laminated. For Pre-K-Grade 2.
