The Kratt Master Key MK2S is a circular chromatic pitch pipe covering the full C-to-C range — all 13 notes of the chromatic scale in one compact, portable tool. It's the go-to reference for choir directors, vocalists, instrumentalists, and music educators who need a reliable, battery-free way to find and confirm pitch.
At its core are 13 hand-tuned bronze reeds housed in patented tone chambers, precision-tuned and double-checked to A-440. The scale is arranged in chromatic sequence, with note notations embossed on both the top and bottom covers so you can quickly find the note you need from either side. The included note selector moves to your target note and physically blocks adjacent holes, so only the pitch you want sounds — no accidental neighboring notes leaking through. The selector also features a ratchet stop action, giving you a positive, tactile click when you land on the right note.
