The P. Mauriat Professional Clarinet series includes four models made from aged grenadilla wood. The 721 series is a 17-key clarinet with either nickel- or silver-plated keys. The 821 series is an 18-key clarinet with either silver- or rose gold-plated keys. Exquisitely built, the clarinets have plenty of ping, as well as the ability to project to the back of the concert hall. All P. Mauriat clarinets utilize premium leather pads and blued-steel springs.
