Because of the diversity of percussive instruments, it is not uncommon to find large musical ensembles composed entirely of percussion.

Rhythm, melody, and harmony are all represented in these ensembles. Music for pitched percussion instruments can be notated on a staff with the same treble and bass clefs used by many non-percussive instruments. Music for percussive instruments without a definite pitch can be notated with a specialist rhythm or percussion-clef.

The guitar also has a special "tab" staff. More often a bass clef is substituted for rhythm clef. Percussion instruments are classified by various criteria sometimes depending on their construction, ethnic origin, function within musical theory and orchestration, or their relative prevalence in common knowledge. The word percussion derives from the Latin verb percussio to beat, strike in the musical sense, and the noun percussus , a beating.

As a noun in contemporary English, Wiktionary describes it as the collision of two bodies to produce a sound. The term is not unique to music, but has application in medicine and weaponry, as in percussion cap. However, all known uses of percussion appear to share a similar lineage beginning with the original Latin percussus. In a musical context then, the percussion instruments may have been originally coined to describe a family of musical instruments including drums, rattles, metal plates, or blocks that musicians beat or struck to produce sound.

The Hornbostel—Sachs system has no high-level section for percussion. Most percussion instruments as the term is normally understood are classified as idiophones and membranophones. However the term percussion is instead used at lower-levels of the Hornbostel—Sachs hierarchy, including to identify instruments struck with either a non sonorous object hand, stick, striker or against a non-sonorous object human body , the ground.

This is opposed to concussion , which refers to instruments with two or more complementary sonorous parts that strike against each other and other meanings. For example:. There are many instruments that have some claim to being percussion, but are classified otherwise:. Percussion instruments are sometimes classified as pitched or unpitched. While valid, this classification is widely seen as inadequate.

Rather, it may be more informative to describe percussion instruments in regards to one or more of the following four paradigms:. Many texts, including Teaching Percussion by Gary Cook of the University of Arizona, begin by studying the physical characteristics of instruments and the methods by which they can produce sound.

This is perhaps the most scientifically pleasing assignment of nomenclature whereas the other paradigms are more dependent on historical or social circumstances. Based on observation and experimentation, one can determine how an instrument produces sound and then assign the instrument to one of the following four categories:. Most objects commonly known as drums are membranophones.

Membranophones produce sound when the membrane or head is struck with a hand, mallet, stick, beater, or improvised tool. Most instruments known as chordophones are defined as string instruments , wherein their sound is derived from the vibration of a string, but some such as these examples also fall under percussion instruments.

Most instruments known as aerophones are defined as wind instruments such as a saxophone whereby sound is produced by a stream of air being blown through the object. Although most aerophones are played by specialist players who are trained for that specific instrument, in a traditional ensemble setting, aerophones are played by a percussionist, generally due to the instrument's unconventional nature.

Examples of aerophones played by percussionists. When classifying instruments by function it is useful to note if a percussion instrument makes a definite pitch or indefinite pitch. For example, some percussion instruments such as the marimba and timpani produce an obvious fundamental pitch and can therefore play melody and serve harmonic functions in music. Other instruments such as crash cymbals and snare drums produce sounds with such complex overtones and a wide range of prominent frequencies that no pitch is discernible.

Instruments in this group are sometimes referred to as non-pitched, unpitched, or untuned. Traditionally these instruments are thought of as making a sound that contains such complex frequencies that no discernible pitch can be heard. In fact many traditionally unpitched instruments, such as triangles and even cymbals, have also been produced as tuned sets. It is difficult to define what is common knowledge but there are instruments percussionists and composers use in contemporary music that most people wouldn't consider musical instruments.

It is worthwhile to try to distinguish between instruments based on their acceptance or consideration by a general audience. For example, most people would not consider an anvil , a brake drum on a vehicle with drum brakes , the circular hub the brake shoes press against , or a fifty-five gallon oil barrel musical instruments yet composers and percussionists use these objects. One preth century example of Mallet Hammer Classification 2020 found percussion is the use of cannon usually loaded with blank charges in Tchiakovsky 's Overture.

By the late 20th century, such instruments were common in modern percussion ensemble music and popular productions, such as the off-Broadway show, Stomp. Rock band Aerosmith used a number of unconventional instruments in their song Sweet Emotion , including shotguns , brooms, and a sugar bag.

The metal band Slipknot is well known for playing unusual percussion items, having two percussionists in the band. Along with deep sounding drums, their sound includes hitting baseball bats and other objects on beer kegs to create a distinctive sound.

It is not uncommon to discuss percussion instruments in relation to their cultural origin. This led to a division between instruments considered common or modern, and folk instruments with significant history or purpose within a geographic region or culture. The general term for a musician who plays percussion instruments is "percussionist" but the terms listed below often describe specialties:.

Within rock music, the term "percussionist" is often used to refer to someone who plays percussion instruments but is not primarily Mallet Hammer Classification Difference a drummer. The term is especially found in bands where one person plays drums and another plays other hit instruments. From Wikipedia, the free encyclopedia.
