I asked my friend, “How would you ask the question?” And he replied, “Hey Google, what do I do if someone stole my tune?” Interesting, I thought, because she could mean different things when she says “my tune.” Particularly in email communication, it’s usually an added step before I know what’s going on; clients expressing a general concept, phrased in a dozen different ways, and subtly they mean different specific things. Someone stole my song. Someone stole my tune. Someone stole my melody, my track, my beat, my flow, my hook, my chorus, my lyrics, my riff, my sample, my loop, my idea — same sense of urgency, frustration, and hurt, but very different claims underneath.
Each of those terms points to a different musical element, and copyright law and forensic musicology treat them differently. Some are squarely protectable and represent the kind of claim courts actually entertain. Some are partially protectable, depending on what was taken and how. Some are hardly protectable at all, and my honest answers disappoint people. But paramount is that everyone is heard, and communication is effective.
So, here’s a general guide. It won’t answer every question, but it ain’t rocket science either. It just addresses the issue. We’ll get some terminology straight, and get a sense of the initial musicological gravity that different terms and phrases engender.
Quick verdict table — (the shorthand)
| What you said, or at least I heard. | What it musicologically is. | Copyright impact? |
|---|---|---|
| Song | The composition (melody + harmony + lyrics + structure) | Yes — probably the strongest term. |
| Tune | Vernacular for the melody, or tune. | Yes. |
| Melody | The pitch sequence over time. So, melody includes rhythm factors. | Yes — the heart of most cases. |
| Track | Raises questions. You could mean the master, the composition, the production, maybe even a single element. | Depends! |
| Beat | The rhythm section or, at least, percussion elements, usually looping, including other instruments, and then separately could refer to the master recording or the underlying instrumental composition. | Yes, but the analysis differs. |
| Flow | Rhythmic delivery and cadence. | On its own, rarely. |
| Hook | The memorable catchy melodic or lyrical phrase. | Yes. Very much yes. |
| Chorus | The repeated section, usually containing the hook. | Yes. |
| Lyrics | The words, a phrase, or more. | Yes, and separately from the music, |
| Riff | A repeated, usually short, melodic-rhythmic figure. | Sometimes. Depends on things like distinctiveness. |
| Sample / loop | A literal piece of audio. | Yes, separate from and in addition to impact associated with the composition. |
| Idea | A concept, theme, or feel | No. It is the expression of an idea that is protectible by copyright, and not simply the idea itself. |
Now the longhand…
Someone stole my song.
“Song” is the umbrella term. When someone says their song was stolen, they usually mean some combination of melody, lyrics, and structural arrangement was copied. This is a relatively strong framing for a claim. Copyright protects the composition as a whole of course, and infringement analysis can draw on multiple elements.
But of course, it’s partly a misnomer. The question that comes next is always the same: which part? Analyzing them separately is how forensic musicology works or at least begins. A case never turns on “the whole song” but on specific identifiable elements that can be compared note-for-note, word-for-word, and phrase-for-phrase against the prior work. But compared to these other terms and phrases, this one is strongest out of the gate. What should you do if someone “stole your song?” Musicologize wrote this bestseller years ago, and it remains indeed “The fiive steps to take if someone stole your song.”
Someone stole my tune.
“Tune” is vernacular for melody, or at least that’s the older usage, so, musicologically, it’s identical to a melody claim. If you’ve described what was taken as “the tune,” what you mean musicologically is the sequence of pitches, their rhythmic placement, and their duration.
Newer usage, however, is synonymous with “song.” Cranking some tunes, you’re probably not separating and soloing vocal stems.
Someone stole my melody
Melody is where the most consequential music copyright cases have lived. A melody is a sequence of pitches over time, and forensic analysis evaluates the contour (the shape of pitch movement), the specific intervals between notes, the rhythmic placement of those notes within the meter, and the harmonic context in which the melody sits.
What a court, and a forensic musicologist, actually looks at is a defined musical phrase, often just four to eight measures, compared against a defined phrase in the prior work. Similarity at the level of contour plus specific pitches, plus rhythmic placement, plus harmonic underpinning, and even more subtle aspects, and then it starts to look like a case. Similarity at the level of contour alone is usually not enough.
If you believe a melody of yours was copied, this is probably the most common sort of observation we look at, and melodic similarity can certainly become the foundation of a case.
Someone stole my track
“Track” is probably the most ambiguous term on this list. It can mean different things with different remedies:
- The master recording, where, in our context, someone used your actual audio file. This is a sound recording copyright issue, and the remedy can be a DMCA takedown and a sound recording infringement claim, that may or may not involve the underlying composition.
- The composition — someone to some extent re-recorded the same melody and chord progression, possibly with different instruments. That somewhat distinguishes the underlying composition concept. We’re talking about the song as notes and chords. It would be the song as its sung, or played by an orchestra, or a kazoo quartet.
Someone stole my beat
Like track, only a bit more narrow. “Beat” almost always means one of two things. Either someone yanked the actual audio file, the “master,” off YouTube or SoundCloud or wherever and created a new work atop it without buying a license. Or it might mean someone re-created the same drum pattern, melodic loop, and harmonic structure as a separate production. Again, it could mean the master or the composition or both.
Again, if it’s a master theft issue. You can pursue takedown notices to streaming platforms, and a sound recording infringement claim. Forensic musicology confirms it’s the same audio.
The second is a composition claim, and that’s more complex. Very, very generally, drum patterns alone are only weakly protectable, but as you stack similar melodic and harmonic content, a claim can emerge. It’s mostly like any other composition claim; what specific musical material was copied, how comprehensive and distinctive; and therefore how protectable by copyright.
This sort of claim is becoming increasingly common, paticularly in commercial contexts — ads, sync placements, brand campaigns — and it’s as often pre-release as it is pre-litigation. See music copyright clearance for advertising.
Someone stole my flow
This is the section that disappoints people most often, but it’s the most important one to read carefully. Maybe a little explanation here will save time and angst.
Flow is mostly rhythmic delivery — the cadence of a vocal performance against the underlying beat, the rhyme placement, the pacing of syllables. Flow can be very distinctive, but frustratingly, on its own, flow is rarely protectable under copyright. Rhythm in isolation usually doesn’t clear the originality threshold that copyright conventionally requires. It’s reasonable, as the law usually is; two rappers can independently arrive at similar cadences over similar tempos, and this sort of coincidence is not infringement. Coincidence and infringement are somewhat opposites.
What more readily becomes protectable is flow in combination: cadence plus specific pitch contour (rappers do pitch their delivery if not the same singers), plus distinctive rhyme schemes, signatures, and lyrical phrasing. When all of that gets copied as a unit, you’re less talking about a flow claim and more about a composition claim.
The response to “someone stole my flow” is still usually my follow-up: what else did they take? When Soulja Boy says: “That’s my bar. He copied my whole fucking flow. He copied my whole fucking flow. Word for word. Bar for bar,” he’s describing more than flow as I’ve defined it. So, here again, terminology can fail us.
Someone stole my hook
Hook” is maybe the opposite. Hooks are where successful music infringement cases concentrate. The reason is structural: a hook is engineered to be memorable, typically short, melodically distinctive, and rhythmically locked. Those are the same properties that make a copying claim both appealing, rightly or wrongly, and sticky, rightly or wrongly.
Forensic analysis of a hook claim looks at the melodic contour, the specific pitches, the rhythmic placement against the meter, the harmonic underpinning, and the lyrical setting where lyrics are present. The qualities that lead readily to observations of similarity and suspicion or convction around copying are pretty aligned with what gives a musicological analysis teeth. Even a two-bar hook with a distinctive contour and a specific rhythmic profile is the kind of musical material that can be compared cleanly against a prior work and yield a defensible conclusion.
Someone stole my chorus
A chorus dovetails with the hook, but usually contains the hook plus surrounding melodic and lyrical material. Chorus claims are evaluated on the same dimensions as hook and melody claims, with the added factor that the lyrical content of a chorus is often what listeners remember most clearly. That means chorus claims frequently combine a melody claim and a lyrics claim into one stronger composite.
Someone stole my lyrics
Lyrics are protected as a distinct element of a musical composition, and they’re also protected as text. Words can be compared directly without the layer of interpretation that musical analysis requires. When lyrics and melody were copied together, the combination of a specific lyric set to a specific melodic phrase is among the strongest forms of infringement claim, less likely to arise from independent creation. Lyricists and music composers used to pair up to form songwriting duos, like Bacharach and David, but nowadays it’s David and Suno! A lyricist can create the words and let AI compose and even perform the song. And therefore, Musicologize is looking at the copyright issues that arise when the copyright office requires human authorship to register a copyright, but the song that results from a partnership between an AI generator and a lyricist can be both protectable and infringed upon. Interesting times.
Someone stole my riff.
A riff is a short repeated melodic-rhythmic figure, usually instrumental, and often distinctive enough to identify the song from its first few seconds. The protectability question for a riff comes down to myriad factors. A riff built from common-stock blues or rock vocabulary is hard to claim ownership of. A riff with an unusual interval pattern, a non-obvious rhythmic profile, or a specific harmonic context can be much more defensible. But brevity and protectability are negatively correlated. So, while, like attorneys, we hate to say “it depends” as much as clients hate to hear it, we sometimes have to say it anyway, because it depends.
Someone stole my sample or loop
Sampling is a different category of issue. OR it SHOULD BE at least. The question isn’t whether two pieces of music sound similar, but whether actual audio was taken and reused. If it was, that’s just about it. There’s the concept of de minimis, but a little bit of sampling is still sampling.
Forensic musicology can help in cases where it’s disputed whether a sample was used at all (versus an interpolation, which is a re-performance of similar material). The analysis distinguishes between literal audio reuse and re-creation. See the Musicologize article: “Say what you mean: interpolation, sampling, or similarity? Let’s get them straight.”
Someone stole my idea
Copyright does not protect ideas. There are few clearer rules in copyright. Copyright protects specific expression of ideas. A song concept like “a breakup ballad set in a diner,” “a love song addressed to a city,” or “a track that combines trap drums with a baroque string sample” is an idea, and ideas are free for anyone to use.
What’s protectable is the specific musical and lyrical expression of the idea. If two artists independently write breakup ballads set in diners, neither has a claim against the other on that basis. If one of them copies the specific melody, lyrics, or distinctive musical material of the other’s expression, that’s a different conversation because at that point the claim isn’t about the idea, it’s about the compositional elements, the expression of the idea.
What to do next
If you believe a specific musical element of yours was copied, the procedural next steps are the same regardless of which element it is: document, register, preserve evidence, talk to a lawyer, and talk to a musicologist. Get help in deciding whether to pursue the claim.
If the question is whether the copying you suspect is musically demonstrable; whether a forensic analysis would actually support the claim; that’s Musicologize.
If you’re earlier in the process and trying to figure out who to engage and how, how to find a forensic musicologist covers the landscape, and how much a forensic musicologist costs covers what to expect on rates and engagement structure. And above all, call, email, or set up an appointment. Every case is unique, and there’s no substitute for talking through it.
