Is a Piano a String Instrument?

Is a Piano a String Instrument?

Many people often wonder about the classification of the piano. Is it a percussion instrument because we hit the keys to produce sound, or a string instrument due to the strings inside it? This document delves into the categorization of the piano in the world of music, revealing its intricate design and the principles that make it a unique musical instrument.

How Does A Piano Work?

A piano operates on the principle of sound production through string vibration. When a player presses a key, it activates a hammer inside the piano, which then strikes a string. These strings are tightly wound and each corresponds to a specific note. The vibration of the string resonates through the piano’s soundboard, amplifying the sound. The player can modify the sound by using pedals, which change the string’s length or tension. So, while the player does hit keys to produce sound (a characteristic of percussion instruments), the sound is created by vibrating strings (a characteristic of string instruments). The piano’s uniqueness stems from the harmonious combination of these actions. [1]

Why Can A Piano Be Considered A Percussion Instrument?

The piano can be categorized as a percussion instrument as it produces sound through a unique mechanical mechanism. The categorization of pianos into percussion instruments is because they produce sound when a specific part of the instrument is struck. When a key is pressed on the piano, the hammers inside strike the strings to produce sound. The act of striking, a defining feature of percussion instruments, is what bestows upon the piano its inherent duality. It is a fascinating fusion of the qualities found in both string and percussion instruments, resulting in a truly unique combination. The piano’s remarkable fusion of elements contributes to its extensive range and dynamic capabilities, rendering it one of the most versatile musical instruments in the world.

Why Can A Piano Be Considered A String Instrument?

The piano is also considered a string instrument because of the vital role played by the strings in producing sound. Inside each piano, there is a complex network of strings, each corresponding to a different musical note. These strings are stretched tightly across a metal frame, and when a piano key is pressed, it causes a hammer to strike a specific string. This action causes the string to vibrate at a singular frequency, resulting in the creation of a unique and melodious musical note. The implementation of this mechanism, which utilizes string vibrations for sound generation, brings the piano in line with other string instruments like violins or guitars. In these instruments, the vibration of the strings is also the primary means of producing sound. Hence, although the piano exhibits characteristics of percussion instruments, its profound dependence on strings to produce musical tones warrants a compelling argument for its classification as a string instrument as well. [2]

The Different Types Of Instruments

Instruments can be broadly categorized into four types: Percussion, Woodwind, Brass, and Strings.


Woodwind instruments are a family of musical instruments within the more general category of wind instruments. The production of sound is achieved by directing air against a sharp edge or reed, resulting in the vibration of the air within their resonant chamber. This family includes instruments such as the flute, clarinet, oboe, saxophone, and bassoon. Each woodwind instrument has its own unique mechanism and method of sound production. Flutes produce sound as players blow air across the instrument’s opening, while clarinets and saxophones utilize a single reed connected to a mouthpiece. On the other hand, oboes and bassoons employ a double reed. Each of these methods results in a distinctive sound, contributing to the rich diversity of music. Thus, from orchestras to jazz bands, woodwind instruments have an essential role, offering a wide range of notes and tonal qualities.



Percussion instruments encompass a wide variety of musical instruments that generate sound using striking, shaking, or scraping. This category is known for its immense variety, encompassing instruments as different as drums, xylophones, tambourines, maracas, and pianos. Each of these instruments generates sound through the vibration of their material, whether it be a drum skin, wooden bar, or metal cymbal. Percussion instruments are fundamental to many music styles, from classical symphonies to jazz bands, and rock concerts to tribal dances. They provide rhythm, texture, and sometimes melody in a musical piece. Some percussion instruments, like the timpani or xylophone, can play specific notes and contribute to the harmonic structure of the music. Others, like the snare drum or cymbals, contribute more to the music’s rhythmic and textural layers. Despite their differences, all percussion instruments share the primary characteristic of producing sound through impact, making them a vital and dynamic part of the musical world. [3]


String instruments, commonly known as chordophones, produce sound through the vibration of their strings. The strings may be plucked, as in a guitar or harp; bowed, as in a violin or cello; or struck, as in a piano. The string’s vibration is transferred through the bridge to the body of the instrument, which amplifies the sound. The pitch of the note can be altered by changing the string’s tension, length, or mass. Instruments such as the guitar and violin use the fingers to change the length of the string, while the piano uses a unique mechanism of hammers striking varying lengths of string. This category of instruments includes a wide array of instruments, from the delicate harp to the versatile guitar, the majestic cello, and the powerful piano. String instruments are integral to many genres of music, capable of producing a wide range of tones and sound effects, from the softest melodies to the most powerful fortissimos. Renowned for their exquisite, melodious, and emotive tones, they have become a beloved choice for orchestras, bands, and solo performances across the globe.


Brass instruments belong to a family of musical instruments that create sound through the harmonious vibration of air in a tubular resonator, in sync with the vibrations of the player’s lips. Brass instruments, known as labrosones, derive their name from their unique method of sound production through lip vibration. This group includes instruments such as the trumpet, trombone, tuba, French horn, cornet, and bugle. To produce sound, each of these instruments necessitates the player buzzing their lips into a mouthpiece. The resulting sound is then amplified and shaped by the instrument’s tubing and bell. The pitch can be changed by adjusting the lip tension or by altering the length of the tubing, either through extending a slide (as in the trombone) or pressing valves which open additional lengths of tubing (as in the trumpet or tuba). Brass instruments are known for their powerful and brilliant tone, making them well-suited to both melodic roles and providing fanfare or accents. They are an integral part of orchestras, bands, and are often featured in solo performances. [4]



Is A piano A string or a Percussion instrument?

The piano is a unique instrument that falls into the classification of both string and percussion. The reason it is classified as a string instrument is because the sounds it produces are created by strings with different lengths and tensions. Similar to a guitar or violin, these strings vibrate to produce the beautiful sounds we hear. However, the piano is also categorized as a percussion instrument due to how the sound is produced. When a piano key is pressed, it triggers a hammer to strike a string, and this action of striking resembles the technique used in percussion instruments. Therefore, the classification of the piano can depend on the context, but it is generally accepted as belonging to both categories.

Which musical instrument is a piano?

The piano, a remarkably versatile musical instrument, defies categorization, bridging the realms of both strings and percussion. The piano operates on the principle of strings and hammers.

This combination puts the piano in a unique position, straddling the line between the string and percussion families of musical instruments. Its wide range, expressive capabilities, and central role in many musical genres further underline its importance and singular nature. Indeed, a piano can be classified as both a string instrument and a percussion instrument. Due to its distinctive features and role, it stands out as a crucial and beloved instrument in the world of music.

Does a piano have strings or wires?

Yes, a piano does have strings, which are also commonly referred to as wires. Inside a piano, there are typically over 200 strings made of high-quality steel. These strings are grouped in sets to enhance the richness and volume of the sound. Pressing key sets in motion a chain of events: a hammer mechanism strikes the strings, setting them in motion and unleashing a symphony of vibrant sounds. The length, diameter, and tension of the string determine the pitch of the note. Despite being referred to as ‘wires,’ they are essentially the ‘strings’ that make a piano a string instrument, in addition to its classification as a percussion instrument due to the hammer-striking action. So, while the terminology may vary, it can be concluded that pianos do have strings, which contribute significantly to its unique sound. Regardless of whether we classify a piano as a string instrument or a percussion instrument, it undeniably holds an iconic and indispensable status in music across diverse genres worldwide.
