C.A. Seydel Söhne Nonslider Chromatic Solo C

No moving parts, strong and rust-resistant materials, no valves (in Solo-C version). You can clean it by pouring tap water inside. Throw it in a backpack, play it cold, store it wet: no problem.

Rustic instrument, yet it responds to soft breath consistently across the range. The reeds produce bright tones if slightly strident, similar to a Seydel Saxony but less "full". Holes are smaller but spaced like a normal harmonica.

Recommended for beginners *if* you pick up a slider chromatic to practice alongside with it. You will appreciate ease of play and consistency, it is a forgiving instrument.
Advanced players will appreciate the challenge of adapting their playing technique.

Important note: some versions of the Nonslider are valved, check Seydel's website.
