arpeggiationfor

Arpeggiation is a musical technique in which the notes of a chord are played in sequence rather than simultaneously. The term derives from the Italian arpeggiare, meaning to pluck like a harp. Notation commonly uses a vertical wavy line before the chord, or the instruction arpegg., indicating a rolled chord. The arpeggiation may ascend or descend, and composers may specify exact order, speed, or range.

In piano music, arpeggios spread a chord across the keyboard, allowing the harmony to unfold and often supporting legato singing lines with the pedal. In guitar playing, arpeggios are realized as picking or fingerstyle patterns that trace chord tones across strings; the same idea appears in strings, winds, and brass when rapid chord-tones are required. In improvisation and harmonic practice, arpeggios are core building blocks, especially for extended or altered chords in jazz. Players may use arpeggios of seventh, ninth, eleventh, or altered varieties to outline harmony. Common practice includes playing arpeggios upward, downward, or in sequences, and combining multiple arpeggio shapes with scale runs.

In modern production, arpeggiators and MIDI effects automate arpeggiation, generating repeating patterns from a held chord. These tools can vary in order, timing, and note length, enabling rapid creativity across genres. The term arpeggiationfor appears to be a concatenation rather than a standard term; if encountered, it likely refers to arpeggiation for a particular instrument or context.
