Jews Harp with two reeds, tuned to different keys, giving common musical intervals - m2/M2/m3/M3/P4/P5 (this sequence demonstrated in audio samples). Very unusual sound produced due to combining two shifted natural harmonic scale, playing both reeds at once, especially considering specific timbre of Glazyrin's jews harps. Separate strokes are possible too, but not very handy.
