The missing semitone for your sound journey

With the Soundbellows Chromatic Extension Set Basic by Reinhardt, you complete your diatonic bellows set with five finely tuned semitones for a full chromatic octave. Ideal for music educators, nurseries, primary schools and elementary music education that want to combine sound, colour and movement.

Colour-coded and intuitive – suitable for every age group

Each of the five Soundbellows is coded to the established Chroma Notes colour scheme, so melodies and music theory can be grasped visually even without reading notation. The squeeze technique is instantly accessible: how firmly and how long you press determines volume and note length, giving a direct, sensory access to sound.

Robust for daily use in groups and lessons

The hard-wearing material withstands daily use in nurseries, schools or music therapy settings. Thanks to its compact size, the set is easy to transport and store, and cleaning between sessions is simple.

• Full chromatic scale: Five semitones complete your diatonic set into a full octave.
• Visual learning: Chroma Notes colour coding makes notes recognisable at a glance.
