Concertinas can be divided into 2 categories
Hybrid Concertinas
Hybrid concertinas feature accordion type reeds, rather than concertina reeds.  Accordion reeds are more economical to produce, and are less sensitive to acoustic design requirements and materials. Because accordion reeds require more space, hybrid concertinas are sometimes larger than their traditional counterparts. Accordion reeds are produced in several qualities.

Our Starter and Intermediate concertina models are hybrid concertinas, featuring accordion reeds.
Traditional Concertinas
Traditional concertina reeds look and perform differently from accordion reeds. They are more complicated and expensive to produce.
Concertina reeds are very acoustic-design sensitive, and their harmonic performance is affected by differences in chamber and cavity materials and design. Concertina reeds are used in vintage concertinas and all Wakker models.

All Wakker Concertina models are traditional concertinas.
