Chalumeau is a medieval single-reed instrument. I make mine in turned swedish birch with a purchased customized mouthpeace with ligature and capsule. This means you can buy your reeds in a "regular" music store selling clarinet reeds. I use hardness grade 1. The instrument has 8 holes on the top and 2 on the bottom.After various developments over the centuries, this instrument became the modern clarinet.
I make it in C major (key-note at the bottom) or G-minor (key-note in the middle). It comes with fingering cart and case.

The price is 1.500 SEK
