In music, counterpoint is the relationship between voices that are harmonically interdependent (polyphony), but independent in rhythm and contour. It has been most commonly identified in classical music, developing strongly during the Renaissance and in much of the common practice period, especially in Baroque music. The term originates from the Latin punctus contra punctum meaning "point against point".

In its most general aspect, counterpoint involves the writing of musical lines that sound very different and move independently from each other but sound harmonious when played simultaneously. In each era, contrapuntally organized music writing has been subject to rules, sometimes strict. By definition, chords occur when multiple notes sound simultaneously; however, harmonic, "vertical" features are considered secondary and almost incidental when counterpoint is the predominant textural element. Counterpoint focuses on melodic interaction—only secondarily on the harmonies produced by that interaction. In the words of John Rahn:

Born in McComb, Mississippi, and raised in Kentwood, Louisiana, Spears began performing as a child, landing acting roles in stage productions and television shows. She signed with Jive Records in 1997 and released her debut album ...Baby One More Time in 1999, which became the best-selling album by a teenage solo artist. During her first decade in the music industry, she became a prominent figure in mainstream popular music and popular culture, followed by a much-publicized personal life. Her first two albums established her as a pop icon and broke sales records, while title tracks "...Baby One More Time" and "Oops!... I Did It Again" became international number-one hits. Spears was credited with influencing the revival of teen pop during the late 1990s, and became the 'best-selling teen aged artist of all time' before she turned 20, garnering her the honorific title of "Princess of Pop".

Glenn Herbert Gould (September 25, 1932 – October 4, 1982) was a Canadian pianist who became one of the best-known and most celebrated classical pianists of the 20th century. He was particularly renowned as an interpreter of the keyboard music of Johann Sebastian Bach. His playing was distinguished by remarkable technical proficiency and capacity to articulate the polyphonic texture of Bach’s music.

Gould rejected most of the standard Romantic piano literature and, after his adolescence, avoided Liszt, Schumann, and Chopin. Although his recordings were dominated by Bach, Gould's oeuvre was diverse, including works by Beethoven, Mozart, Haydn, Brahms, pre-Baroque composers such as Jan Sweelinck, and such 20th-century composers as Paul Hindemith and Arnold Schoenberg. Gould was well known for various eccentricities, from his unorthodox musical interpretations and mannerisms at the keyboard to aspects of his lifestyle and personal behavior. He stopped giving concerts at the age of 31 to concentrate on studio recording and other projects.

Stephen Michael "Steve" Reich ( /ˈraɪʃ/; born October 3, 1936) is an American composer who is one of the pioneering composers of minimal music along with La Monte Young, Terry Riley, and Philip Glass.

His innovations include using tape loops to create phasing patterns (examples are his early compositions, "It's Gonna Rain" and "Come Out"), and the use of simple, audible processes to explore musical concepts (for instance, "Pendulum Music" and "Four Organs"). These compositions, marked by their use of repetitive figures, slow harmonic rhythm and canons, have significantly influenced contemporary music, especially in the US. Reich's work took on a darker character in the 1980s with the introduction of historical themes as well as themes from his Jewish heritage, notably the Grammy Award-winning Different Trains.

Reich's style of composition influenced many other composers and musical groups. Reich has been described, in The Guardian by music critic Andrew Clements, as one of "a handful of living composers who can legitimately claim to have altered the direction of musical history", and the critic Kyle Gann has said Reich "may...be considered, by general acclamation, America's greatest living composer."
