The jSax follows traditional saxophone fingering patterns and allows children to develop the embouchure and playing skills of a saxophone from an early age. It has a surprisingly soft saxophone sound and is enjoyable even for an experienced amateur saxophonist. Like all other Nuvo instruments, the jSax is tuned in C, allowing it to play along with all WindStars music pieces. It has a fully chromatic range from middle C to G in the next octave. For beginners with small fingers, there is a set of plugs that can seal the tone holes during the first days of learning.

The jSax is lightweight, highly durable, and 100% waterproof, making it suitable for both lessons and travel. It uses standard Nuvo clarinet reeds in strengths 1/2 and 2, which are included. It can also use an E clarinet reed, and some soprano sax mouthpieces fit as well. You might also want to try the synthetic reed from Légère, which fits all Nuvo instruments. The jSax comes with a sturdy, blow-molded case, a carrying strap, and a fingering chart.
