The Rainbow Notes Percussion Set features 8 brightly colored tone bars or bells, each tuned to a different note of the diatonic scale (C–C). Whether in the form of metal bells, xylophone bars, or domed percussion pads, each color corresponds to a specific pitch–making it easy for children to learn melody, sequence, and harmony through sight and sound. Rooted in Montessori's sensorial and auditory development and Waldorf's artistic approach to rhythm and tone, this instrument set nurtures an early love for music while supporting cognitive and motor skill growth.
