This is a smaller, expansion set of hand chimes that has been created to work in addition to the HB-250, HB-12A 3rd octave expansion kit and HB-12B 4th octave expansion kit sets of chimes.
The HB-250 is the core set of 25 notes which encompass G4 - G6. The HB-12A expands this set at both the bottom and the top. The HB-12B further expands the range at both ends whilst the HB-7 expands yet again at the bottom from CC3 - F#3.
It is important to remember that this HB-7 set is designed to complement the HB-250 and the HB-12A and the HB-12B and is therefore not necessarily something to purchase as a standalone product. As with all Suzuki Tonechimes, quality is superb with a bell like tonal resonance and a lightweight construction. They are also supplied in a solid protective hard case.
The above figure shows the range of the tone chime displayed in staff notation. The "8va" symbol above the clef in this image is omitted in the tone chime sheet music. In addition, the symbol is omitted in the display of the staff ntoation written on the main body of teh tone chime.
