This is a smaller, expansion set of hand chimes which 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 G35 - G59. 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 C16-F#22.
It is important to remember that this HB-7 set is designed to compliment 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.
