The Soundbellows SBS-DH Diatonic Set,here in the High version, consists of eightcolor-codedhand bellows that together form a diatonicscale (c3-c4). They expand the Orff instrumentarium with instruments whose tones can be varied in volume and length, depending on how hard or long you press the bellows in. Each Soundbellow has a specific color to match its tone, so music theory and melodies can be taught and learned with an additional visualcontext. In addition, all Soundbellows are also labeled with their respective note and indicate with the color of their cap also directly the position (gray=high position). The notation follows the internationalstandard, so that the note B corresponds to the German H.
