Wood scraper block

A wood scraper block, also known as wooden agogo or tone wood block, is an idiophone percussion instrument.

It consists, usually, in a pair of small tubes made of wood, each one of different size, producing different tones.

These tubes are played with a stick and have a ribbed surface to double as scraper.

Originally proposed by Matin Cohen from Latin Percussion, imitating a Brazilian agogô and Latin güiro, this instrument is also manufactured with a single block or with three blocks.
