The Two-Tone Block is a percussion instrument used in bands. Each wooden, cylindrical side is hollowed out, and tuned to a different pitch. This is similar to the tuned Chinese temple blocks. When played with a wooden beater, the two-tone block gives a bright and penetrating sound with a certain hollowness not found in claves.
