Copyright basics: what it protects and when it begins
Your copyright begins the moment you write the song down, hit record, save the file, or export the render. Not when you register it. Not when you publish it. Not when you put a © on it.
The Copyright Office says it plainly: "Copyright protection in the United States exists automatically from the moment the original work of authorship is fixed."
That is the whole trigger. Two conditions — original, and fixed — and you own something.
The two requirements: original and fixed
Section 102(a) of the Copyright Act protects "original works of authorship fixed in any tangible medium of expression, now known or later developed."
Original is a lower bar than most people assume, and a different bar than most people assume. The Supreme Court defined it in Feist Publications v. Rural Telephone as "independent creation by the author (as opposed to copied from other works)" plus "at least some minimal degree of creativity." It does not mean novel. It does not mean good. It means you made it yourself and there is some creative spark in it.
It also does not mean hard. Feist explicitly rejected the "sweat of the brow" theory — the idea that effort alone earns protection. The Court's line: "copyright rewards originality, not effort." You can spend six months compiling a database and own very little of it.
Fixed is defined in §101: a work is fixed when its embodiment in a copy or phonorecord, by or under the authority of the author, is "sufficiently permanent or stable to permit it to be perceived, reproduced, or otherwise communicated for a period of more than transitory duration."
Practically: a melody you have only hummed is not fixed. A voice memo of that melody is. An improvised set that nobody recorded is not fixed. The same set, recorded with your authorization, is.
The Act also tells you when a work is "created" — §101 says a work is created "when it is fixed in a copy or phonorecord for the first time," and if you build it over time, "the portion of it that has been fixed at any particular time constitutes the work as of that time." Your rough cut is protected as a rough cut while you keep working.
What counts as a work of authorship
Section 102(a) lists eight categories:
Literary works
Musical works, including any accompanying words
Dramatic works, including any accompanying music
Pantomimes and choreographic works
Pictorial, graphic, and sculptural works
Motion pictures and other audiovisual works
Sound recordings
Architectural works
One thing musicians should internalize early: a recorded song is two copyrights. The musical work — melody and lyrics — is category 2. The sound recording — that specific captured performance — is category 7. They can be owned by different people, they are licensed separately, and they are registered separately.
The bundle: six exclusive rights
Owning a copyright means owning a set of rights, not one right. Section 106 gives the owner the exclusive right to do, and to authorize others to do, six things:
Reproduce the work in copies or phonorecords
Prepare derivative works based on it
Distribute copies or phonorecords to the public by sale, other transfer of ownership, rental, lease, or lending
Perform it publicly — for literary, musical, dramatic, and choreographic works, pantomimes, and motion pictures and other audiovisual works
Display it publicly — for literary, musical, dramatic, and choreographic works, pantomimes, and pictorial, graphic, or sculptural works, including individual images from a motion picture
Perform sound recordings publicly by means of a digital audio transmission
Read 4, 5, and 6 carefully. Sound recordings do not get a general public performance right — only the digital audio transmission right in (6). That is why terrestrial radio pays songwriters and publishers but not the recording artist, and why streaming works differently.
These rights are divisible. You can license the sync right to a film and keep everything else. You can grant exclusive distribution in one territory and non-exclusive elsewhere. Think of it as six separate assets you can sell, license, or keep.
All six are also "subject to sections 107 through 122" — the limitations and exceptions, including fair use. The rights are exclusive, not absolute.
The line copyright will not cross: idea versus expression
Section 102(b) is the most important sentence in the Act for working creators:
"In no case does copyright protection for an original work of authorship extend to any idea, procedure, process, system, method of operation, concept, principle, or discovery, regardless of the form in which it is described, explained, illustrated, or embodied in such work."
Copyright protects how you said it, never what you said it about.
Your screenplay about a heist crew of retired opera singers is protected. The concept of a heist crew of retired opera singers is not. Your instructional video on a mixing technique is protected. The technique is not. Your podcast episode reporting five facts is protected as a piece of writing and speech; the five facts belong to everyone.
That is Feist again: "No one may claim originality as to facts," because facts "do not owe their origin to an act of authorship." The Court framed it as "the distinction between creation and discovery."
What copyright does not cover
The Copyright Office's Circular 33 catalogs the exclusions. The ones creators hit most often:
Names, titles, short phrases, and slogans. Circular 33: "Words and short phrases, such as names, titles, and slogans, are uncopyrightable because they contain an insufficient amount of authorship." That covers band names, album titles, film titles, product names, domain names, character names, and catchphrases. Some of these can be protected as trademarks — a different body of law with different requirements — but not by copyright.
Familiar symbols and designs. "Familiar symbols and designs, or a simple combination of a few familiar symbols or designs, are uncopyrightable" — letters, numbers, arrows, stars, common geometric shapes.
Typeface. "Copyright law does not protect typeface or mere variations of typographical ornamentation or lettering." (The font software is a separate question.)
Blank forms. "Blank forms that are designed for recording information and do not themselves convey information are uncopyrightable."
Useful articles. Section 101 defines a useful article as one "having an intrinsic utilitarian function that is not merely to portray the appearance of the article or to convey information." The design of a useful article is protectable "only if, and only to the extent that, such design incorporates pictorial, graphic, or sculptural features that can be identified separately from, and are capable of existing independently of, the utilitarian aspects of the article." A chair is a chair. A sculptural element on the chair that could stand alone as art may be protected.
How long it lasts
For works created on or after January 1, 1978, §302 sets the term:
Single author: life of the author plus 70 years.
Joint works: life of the last surviving author plus 70 years.
Anonymous works, pseudonymous works, and works made for hire: 95 years from first publication or 120 years from creation, whichever expires first. (An anonymous or pseudonymous author who later reveals their identity on Office records can convert to the life-plus-70 term.)
And §305 handles the calendar: "All terms of copyright provided by sections 302 through 304 run to the end of the calendar year in which they would otherwise expire." Terms end on December 31, never mid-year.
Works created before 1978 run on a different set of rules under §§303 and 304 — if you are dealing with an older catalog, that analysis is separate and worth doing carefully.
What to actually do with this
Three habits, and they cost almost nothing:
Fix everything. Voice memos, dated drafts, exported stems, screen recordings. Fixation is the trigger; make it happen early and keep the file.
Keep the record. Creation dates, publication dates, who contributed what. Every downstream question — ownership, term, registration timing, splits — runs on those dates.
Get the ownership in writing before the work exists. Collaborations, commissions, and contractor work all default in ways people do not expect. A one-page agreement signed at the start is cheaper than any of the alternatives.
Copyright arrives free. Registration is a separate step that unlocks enforcement and remedies — that's a different article, and if you are planning to release anything commercially, it is the one to read next.
