Cowbell (instrument) in the context of "Herder"

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.

The washboard and frottoir (from Louisiana French "frotter", to rub) are used as a percussion instrument, employing the ribbed metal surface of the cleaning device as a rhythm instrument. As traditionally used in jazz, zydeco, skiffle, jug band, and old-time music, the washboard remained in its wooden frame and is played primarily by tapping, but also scraping the washboard with thimbles. Often the washboard has additional traps, such as a wood block, a cowbell, and even small cymbals.

Conversely, the frottoir (zydeco rubboard) dispenses with the frame and consists simply of the metal ribbing hung around the neck. It is played primarily with spoon handles or bottle openers in a combination of strumming, scratching, tapping and rolling.

"4 Minutes" is a song by American singer Madonna from her eleventh studio album Hard Candy (2008), featuring vocals by fellow American singer Justin Timberlake and American producer Timbaland. It was released as the lead single from the album on March 17, 2008, by Warner Bros. Records. It marked the first time in Madonna's 25-year career that another artist was featured in a single. According to Madonna, the song is about saving the environment and "having a good time while we are doing it". She also cited the song as the inspiration for the documentary I Am Because We Are (2008).

The song was recorded at Sarm West Studios, in London, while the mixing of the track was finished at The Hit Factory studio in New York City. Sound engineer Demo Castellon first worked on the vocals and then on the beats, while the synths were composed by Timbaland and Danja. An uptempo dance-pop song with an urban and hip hop style, "4 Minutes" incorporates Timbaland's characteristic bhangra beats and the instrumentation used in the song includes brass, foghorns and cowbells. The lyrics carry a message of social awareness, inspired by Madonna's visit to Africa and the human suffering she witnessed.

A pitched percussion instrument (also known as a melodic or tuned percussion instrument) is a percussion instrument used to produce musical notes of one or more pitches, as opposed to an unpitched percussion instrument which is used to produce sounds of indefinite pitch.

Pitching of percussion instruments is achieved through a variety of means.

Timbales (/tɪmˈbɑːliːz/) are shallow single-headed drums with metal casing. They are shallower than single-headed tom-toms and usually tuned much higher, especially for their size.

Timbales are struck with wooden sticks on the heads and shells, although bare hands are sometimes used. The player (called a timbalero) uses a variety of stick strokes, rim shots, and rolls to produce a wide range of percussive expression during solos and at transitional sections of music, and usually plays the shells (or auxiliary percussion such as a cowbell or cymbal) to keep time in other parts of the song. The shells and the typical pattern played on them are referred to as cáscara. Common stroke patterns include abanico, baqueteo (from danzón), mambo, and chachachá.
