Timbales in the context of "Unpitched percussion"

An unpitched percussion instrument is a percussion instrument played in such a way as to produce sounds of indeterminate pitch, or an instrument normally played in this fashion.

Unpitched percussion is typically used to maintain a rhythm or to provide accents, and its sounds are unrelated to the melody and harmony of the music. Within the orchestra, unpitched percussion is termed auxiliary percussion, and this subsection of the percussion section includes all unpitched instruments of the orchestra however they are played, for example the pea whistle and siren.

Bongos (Spanish: bongó) are an Afro-Cuban percussion instrument consisting of a pair of small open bottomed hand drums of different sizes. The pair consists of the larger hembra (lit. 'female') and the smaller macho (lit. 'male'), which are joined by a wooden bridge. They are played with both hands and usually held between the legs, although in some cases, as in classical music, they may be played with sticks or mounted on stands.

Bongos are mainly employed in the rhythm section of son cubano and salsa ensembles, often alongside other drums such as the larger congas and the stick-struck timbales. In these groups, the bongo player is known as bongosero and often plays a continuous eight-stroke pattern called martillo (lit. 'hammer') as well as more rhythmically free parts, providing improvisatory flourishes and rhythmic counterpoint.

A jam block is a percussion instrument developed as a modern, hard plastic version of the woodblock. They are popularly used for their durability when compared to the traditional woodblock. They were created by Martin Cohen, founder of Latin Percussion, after percussionist Marc Quiñones requested a sturdier version of the woodblock.

Jam blocks are usually attached to timbales and drum kits, but they can also be used as standalone orchestral instruments. They are often used in salsa and other Latin American styles, although some modern drummers have used them in rock. They are also often used to keep time during marching band rehearsals where they are popularly known as "gock blocks".
