Definition
Music, as a subject of legal analysis, is not a term of art with a single fixed definition in law. It appears across several bodies of doctrine — principally intellectual property, licensing, performance regulation, and broadcast law — and the legal significance of the term depends heavily on which body of law is operating.
In intellectual property law, music is treated as two legally distinct objects: (1) the musical composition, comprising melody and lyrics (if any), which is protectable as a literary and musical work; and (2) the sound recording, comprising a specific fixation of a performance of that composition, which is separately protectable. These two objects can be owned by different parties, licensed independently, and implicate different rights. A single song played on the radio involves at least two copyrights.
In licensing contexts, music is the subject of mechanical licenses (for reproducing a composition in a recording), synchronization licenses (for pairing a composition with visual media), public performance licenses (administered by performing rights organizations for broadcast and live performance), and master use licenses (for reproducing a specific sound recording).
In regulatory and municipal law, music — particularly live or amplified music — can trigger noise ordinances, public entertainment licensing requirements, and zoning restrictions.

Common Language
Modern common usage (Wiktionary): A series of sounds organized in time, usually employing some combination of harmony, melody, rhythm, and tempo, often to convey a mood; also, an art form created by organizing pitch, rhythm, and sounds.
Historical common usage (Webster's 1913): The science and art of tones or musical sounds — sounds of higher or lower pitch produced by uniform and synchronous vibrations — comprising the science of harmonical tones and the art of combining tones in a manner to please the ear.
The legal gap is significant. Common usage treats music as a single unified thing. Law fractures it into components — composition versus recording, performance versus reproduction, published versus unpublished — that carry separate rights, separate licenses, and separate ownership chains. A researcher approaching music law with only the common definition will miss the foundational bifurcation that drives most intellectual property disputes in this field.

Common Confusion
The most consequential confusion in music law is treating a song as a single copyrightable object. It is not. Owning the copyright in a composition does not confer rights in any particular recording of it, and vice versa. This distinction underlies the entire structure of music licensing and produces recurring litigation over unauthorized sampling, cover recordings, and synchronization.
A related confusion: a mechanical license grants the right to reproduce and distribute a composition in a new recording. It does not license the original sound recording, and it does not authorize public performance. Each right requires a separate license from a separate rightsholder.

Why It Matters in Research
Researchers approaching music in the Law Mind corpus must hold the composition/recording distinction firmly in mind at all times. Sources from before the mid-twentieth century will often treat music copyright as a single unified right, reflecting the law before sound recording received independent federal protection. The Copyright Act of 1976 and its amendments — including the Digital Performance Right in Sound Recordings Act of 1995 and the Music Modernization Act of 2018 — have substantially restructured who owns what, what licenses are required, and how royalties flow. Pre-1972 sound recordings occupied a legal limbo under state law for decades; researchers dealing with historical recordings should flag this specifically.
Performing rights organization (PRO) licensing — through ASCAP, BMI, and SESAC in the United States — operates under consent decrees with the Department of Justice that are themselves a moving target. Research into performance licensing must account for the regulatory overlay these consent decrees impose, which does not appear in standard copyright treatises.
Jurisdictional variation matters most in two areas: (1) moral rights, which are recognized robustly in civil law countries but narrowly in U.S. law (limited to visual art under VARA, not music); and (2) neighboring rights for performers and producers, which exist under international treaties and many foreign systems but have no direct equivalent in U.S. copyright for domestic purposes.
The Rapalje & Lawrence source provided for this entry contains no entry for music. The dictionary's coverage reflects late nineteenth-century English law, predating both the modern copyright framework and the emergence of sound recording as a legal object. Researchers should not rely on historical legal dictionaries for music copyright doctrine.

Historical Dictionary Support
Rapalje & Lawrence does not contain a substantive entry for music as a legal term. The source material provided is an excerpt from the entry on municipal corporations, confirming the absence of dedicated coverage. This absence is characteristic of the period: nineteenth-century legal dictionaries did not treat music as a distinct category of legal analysis. Copyright protection for musical compositions existed in English and American law by the mid-1800s, but the law had not yet generated the doctrinal complexity — particularly around sound recordings, performance rights, and mechanical reproduction — that would later demand systematic treatment.
Webster's 1913 captures music as a unified art and science of organized sound. The legal literature of the same era would have understood music copyright primarily as protection for printed sheet music, a framing that became progressively inadequate as the phonograph, radio, and eventually digital distribution transformed both the industry and the law.

Jurisdictional Note
U.S. music copyright law differs from most other developed systems in its treatment of sound recordings: the United States does not recognize a general public performance right in sound recordings for terrestrial broadcast (AM/FM radio), though digital performance rights exist. Many countries recognize broader neighboring rights for performers and producers. Researchers working with international sources or multinational licensing arrangements must account for this asymmetry.
