2-Tone: Instruments (usually wooden or metal blocks) that produce two different tonal notes (one high and one low) when struck or scraped.
Agogo: Traditional percussion instrument (often metal, double or single) with a distinctive, piercing sound. It is used extensively in Latin music (e.g., samba) and combines striking with scraping.
Guiro: The classic Latin American percussion instrument with the characteristic grooves on its surface. It is played by scraping it with a stick/comb, producing a “rough” but rhythmic sound.
Güira: The metal version of the Guiro (popular in Merengue music). It is made of steel or sheet metal with a textured surface, producing a much brighter, metallic, and louder sound.
