This is a smaller, expansion set of hand chimes which has been created to work in addition to the HB-250 set of 25 chimes.
The HB-250 is the core set of 25 notes which encompass G35 - G59. The HB-12A expands this set at the bottom, C28-F#34 and at the top G#60-C64.
It is important to remember that this HB-12A set is designed to compliment the HB-250 and is 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.
