Music can play notes one by one. 
Music can play many notes at once. An arpeggio plays those notes one by one. 
Music can sound very full. An arpeggio helps make this happen.
A chord is a group of notes played together. In an arpeggio, you play those notes one by one. The notes can go up or down in order. They can stay in one area or span many octaves.
The word comes from an Italian word. It means to play on a harp. Arpeggios help many kinds of music. They add interest to a song. They can also help a lead melody shine.
Some instruments only play one note at a time. A trumpet is one example. An arpeggio lets a trumpet player sound like a full chord. In old video games, this was very important. The machines had a hard time making many sounds at once. Composers used arpeggios to save space for drums and bass.
Sometimes, many instruments play an arpeggio together. This is called a bell chord. It sounds like bells ringing in a row. 
Music students use them for practice. They help students learn to play with good skill. You can hear them in rock, jazz, and even flamenco music.
An arpeggio is a special way to play a chord. Usually, a chord is a group of notes played at once. In an arpeggio, you play those notes one by one. The notes can go in a rising order. They can also go in a descending order. This technique makes music sound very interesting. It can be used as a pretty decoration for a melody. It can also help create a steady rhythm. Listeners often hear the notes as one full chord if they are played very quickly.
There are many ways to perform an arpeggio. You can play the notes within a single octave. You can also span many different octaves. The notes can overlap or stay separate. Some people call them rolled chords on keyboard instruments. 
The word arpeggio comes from an Italian word. It means to play on a harp. This name fits well because of how the notes flow. 
Arpeggios help instruments that can only play one note at a time. A trumpet is a good example of this. An arpeggio allows a trumpet to sound like it is playing a full chord. This was very helpful for early video game music. For example, the Commodore 64 had a SID chip with only three oscillators. This meant the machine could not play many sounds at once. Composers used arpeggios to save space for drums and bass. Many European composers used this trick on systems like the NES in the 1980s.
Sometimes, several instruments play an arpeggio one after another. This is called a bell chord or a bell effect. It can also be called a pyramid or a cascade. 
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.
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.
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. 
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. 
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.
