Defining Accompaniment

The Foundation of Sound

Musical accompaniment refers to the instrumental or vocal part that provides rhythmic and/or harmonic support for the main melody or themes of a musical composition. It serves as the essential framework upon which the primary musical ideas are built, ensuring a cohesive and engaging sonic experience.

Roles in Musical Texture

In homophonic music, a prevalent style in popular music, accompaniment typically consists of subordinate chords that support a clear vocal or instrumental melody. Conversely, in traditional and popular genres, accompaniment often provides the foundational beat and outlines the harmonic progression of a piece. The complexity of accompaniment parts can range from simple chordal structures suitable for beginners to intricate passages demanding advanced technical proficiency, as seen in the Lieder of 19th-century composers.

The Accompanist's Role

An accompanist is a musician dedicated to performing these support roles. Often proficient on keyboard instruments like the piano or organ, or guitar in folk traditions, accompanists require exceptional sight-reading abilities. This skill is crucial for auditions and rehearsals, where they must interpret new music instantaneously. The term "collaborative piano" is increasingly used to denote the sophisticated musicianship and technical demands of these parts in art songs and contemporary classical works.

Styles and Roles

Homophonic Support

In homophonic music, the accompaniment primarily offers harmonic and rhythmic structure. A clear melody is presented, supported by chords that move together rhythmically. This is the dominant approach in much of popular music, where the accompaniment provides the essential pulse and harmonic foundation for the lead vocal or instrument.

Rhythmic and Harmonic Framework

Across various genres, accompaniment parts are vital for establishing the music's "beat" and delineating the chord progression. This can be achieved through diverse patterns, from simple strummed chords on a guitar to complex rhythmic figures played by a drum kit and bassline.

Dialogue Accompaniment

A specific style known as "dialogue accompaniment" employs a call-and-response structure between the lead and the accompaniment. The accompaniment plays during the rests of the lead part, often providing a drone or silence, creating an interactive musical conversation.

Instrumentation

Chordal and Bass Capabilities

Instruments capable of playing both chords and basslines simultaneously are frequently employed for accompaniment, especially when a single musician provides support. The piano and guitar are prime examples, offering harmonic richness and rhythmic drive.

Ensemble Support

Accompaniment can also be provided by ensembles of varying sizes. A string quartet might accompany a vocalist in classical music, while a rhythm sectionโ€”typically comprising electric bass, drums, and guitar or keyboardโ€”forms the backbone of many rock, pop, and jazz ensembles. Orchestras provide accompaniment for soloists in concertos and singers in opera.

Common Accompaniment Instruments

Instruments frequently utilized for accompaniment include:

  • Piano
  • Pipe Organ
  • Synthesizer
  • Guitar (Acoustic and Electric)
  • Electric Bass
  • Double Bass
  • Drum Kit
  • Hammond Organ

Notation vs. Improvisation

Fully Notated Parts

In classical music and large ensemble arrangements, accompaniment parts are often fully notated on sheet music. This ensures precise execution of the composer's or arranger's intentions, detailing every note, rhythm, and dynamic.

Improvised Accompaniment

In popular and traditional music, accompaniment is frequently improvised. Musicians often work from lead sheets or chord charts that indicate the harmonic structure (e.g., C Major, G7, Nashville Numbers). This allows for greater flexibility and stylistic interpretation, with players improvising rhythms, fills, and basslines based on the provided chords and the overall feel of the piece.

Improvisation requires a deep understanding of harmony, rhythm, and style. Bass players, for instance, might improvise walking basslines over chord changes, while pianists or guitarists might create intricate chord voicings and melodic fills. Tablature (tab) is also used by some instrumentalists to indicate finger placement. Even in arranged music, elements of improvisation might be incorporated, such as a written introduction followed by chord symbols for improvised solos.

Common Accompaniment Figures

Rhythmic and Melodic Patterns

Accompaniment figures are recurring musical patterns that provide texture and drive. These can range from simple broken chords to more complex melodic lines.

  • Alberti Bass: A pattern of broken chords, typically played as low-high-middle-high, providing a flowing harmonic foundation.
  • Ostinato: A continually repeated musical phrase or rhythm, creating a persistent underlying pattern.
  • Riff: A short, repeated musical phrase, often melodic or rhythmic, commonly found in popular music and jazz.
  • Drone: A sustained or repeated sound, often a single pitch, providing a harmonic base.
