Arpeggio

arts Maturity 11-13 Next article →

An arpeggio is a specific type of musical chord. In a standard chord, all the notes sound at the exact same time. An arpeggio changes this by sounding the notes of the chord individually. These notes are played in a progressive rising or descending order.

This technique allows a series of single notes to feel like a single, unified harmony. While the notes are played one after another, listeners often hear them as a full chord if they are played in quick succession. This creates a sense of movement and flow that a static chord lacks.

To perform an arpeggio, a musician follows a specific sequence of pitches. An arpeggio must contain at least three different pitches to be classified as such. If a musician only plays a sequence of two pitches, the sound is actually called a trill or a tremolo.

The notes can be contained within a single octave or they can span multiple octaves. Musicians may also choose to have the notes overlap or keep them entirely separate. On keyboard instruments, these are sometimes referred to as rolled chords. In musical notation, composers often use a wavy vertical line to indicate a very rapid arpeggiated chord. Most players read these from the lowest note to the highest, though a downward arrow can indicate a high-to-low sequence.

There are several distinct ways arpeggios function within a piece of music. They can serve as melodic ornamentation, which acts as a decorative flourish around a main tune. They are also used to create rhythmic interest by adding a sense of pulse or pattern. For instruments that are monophonic, meaning they can only play one note at a time, arpeggios are essential.

A trumpet player, for example, can use arpeggios to "voice" a chord progression. This allows a single instrument to imply the complex harmonies of a full ensemble. Arpeggios can also act as an alternative to portamento, which is a continuous slide between notes. This is especially useful for keyboards, fretted instruments, or flutes that have limitations in sliding smoothly between many notes.

Arpeggios appear in a vast range of musical genres and technical settings. In the world of jazz, they are a fundamental part of improvisation. In guitar playing, musicians use a specific technique called sweep-picking to perform rapid arpeggiation. This style is a staple of rock and heavy metal music. Other genres, such as flamenco and neo-classical music, place a heavy focus on the melody and ornamentation provided by arpeggios. Beyond performance, they serve an educational purpose. Music students use arpeggios alongside scales as basic technical exercises to improve their intonation and overall technique.

The history of the term is rooted in the Italian language. The word arpeggio comes from "arpeggiare," which means to play on a harp. This connection highlights the flowing, cascading nature of the sound.

While the term is Italian, the English plural is typically "arpeggios" rather than the Italian "arpeggi." This technique has even been integrated into modern technology. Some synthesizers include hardware called arpeggiators. These are step sequencers designed to automatically facilitate the playing of arpeggios or other complex sequences.

One of the most fascinating historical uses of arpeggios was in early video game music. During the 1980s, sound hardware was often very limited. For example, the Commodore 64 used a SID chip that only had three oscillators, or voices. This meant a composer could not play many different sounds at the same time. To solve this, they used arpeggios to play chords using only a single channel. This saved the other channels for drums, bass, or sound effects. Many European composers transferred this knowledge to systems like the NES, using arpeggios to create rich textures within strict hardware limits.

A related but distinct technique is known as a bell chord, or "bells." This is a musical arrangement where separate instruments play the individual notes of a chord in a sequence.

Each instrument sustains its note, eventually building a full chord through a cascade or pyramid effect. This technique originated with jazz big bands and remains a staple of traditional jazz. It is also very common in barbershop music. Notable examples of this "bell effect" can be heard in the song "The Charleston" by The Temperance Seven. The rock band Queen also utilized this technique in the middle section of "Bohemian Rhapsody" and during the solo in "Killer Queen."
