The Musical Grammar Copyright Test evaluates whether an apparent similarity belongs to a specific composition or to music's shared vocabulary. Begin by identifying exactly what overlaps: melody, lyrics, harmony, rhythm, groove, or production texture. Then trace that element historically and examine how widely it appears across unrelated works. A recurring chord sequence, groove, or stylistic texture is more analogous to grammar than to a novelist's original sentences. The final test asks what would happen if one creator controlled the element: if ordinary composition would become materially harder, the claim probably reaches beyond distinctive expression. This mechanism does not determine legal liability, but it provides a disciplined way to screen concerns, document prior musical usage, and avoid chilling legitimate creativity.
Origin
Laurence Juber developed this argument through his musicology background and his analysis of disputes such as “Blurred Lines” and “Stairway to Heaven.”
Core principles
- 01Treat common harmony and groove as shared musical vocabulary.
- 02Distinguish a composition's expressive details from its underlying grammar.
- 03Use musical history to test whether an element predates the disputed work.
- 04Protect creators without granting ownership over basic creative building blocks.
How to run it
- 1
Define the alleged overlap
Describe the precise musical feature at issue rather than comparing the works only by overall impression. Determine whether the overlap concerns melody, lyrics, harmony, rhythm, groove, or recorded sound.
Pro tip Transcribe the relevant passages so each musical dimension can be considered separately.
Watch out A vague claim that two songs merely feel alike cannot reveal which element may be protectable.
- 2
Classify the element
Decide whether the feature is distinctive expression or a functional building block used throughout music. Give greater scrutiny to melody and lyrics than to familiar harmonic movements or grooves.
Pro tip Use the grammar analogy: distinguish reusable syntax from the particular statement created with it.
Watch out Do not assume that a prominent or memorable element is automatically original.
- 3
Trace prior usage
Look backward through genres and historical periods for materially similar examples. Repeated independent use indicates that the element belongs to the common musical language.
Pro tip Search beyond recent popular recordings, including folk, Renaissance, Baroque, blues, and other traditional forms.
Watch out Limiting the search to contemporary hits can hide centuries of prior use.
- 4
Test the creative-space impact
Ask whether granting control over the feature would prevent others from using ordinary compositional tools. Treat a severe restriction on future creativity as evidence that the claimed scope is too broad.
Pro tip Imagine applying the same ownership rule consistently across an entire genre.
Watch out This policy test informs analysis but does not override the governing law.
- 5
Escalate distinctive cases
If the overlap remains unusually specific after historical comparison, document it and obtain expert legal and musicological review. Preserve both the similarities and meaningful differences.
Pro tip Use independent experts who can explain the music clearly to non-musicians.
Watch out Do not present this screening framework as a definitive legal opinion.
In the wild
A songwriter discovers that a new introduction resembles an older recording. The review separates the descending harmony from its melody and searches historical repertoire, finding comparable sequences in Baroque works and many later songs. The songwriter retains the harmony but changes a melodic phrase that is much closer to the recent recording.
→ The song preserves a useful shared progression while reducing the risk attached to distinctive expression.
A producer worries that a track's rhythmic feel resembles a Motown record. The team documents the groove, compares it with numerous recordings, and separates the general rhythmic pattern from any sampled audio, copied melody, or distinctive arrangement detail.
→ The team identifies which elements are generic stylistic vocabulary and which require modification or clearance.
Common mistakes
Judging only by overall feel
A shared mood or groove can conceal major differences in melody and lyrics. Break the comparison into discrete musical elements before reaching a conclusion.
Ignoring musical history
A sequence may sound associated with a modern hit while having centuries of prior use. Historical comparison is central to identifying common vocabulary.
Treating the test as legal advice
The framework is an analytical screen, not a ruling on infringement. Close cases require qualified legal and musicological expertise.
Is it for you?
Best for
It is best for songwriters, producers, musicologists, and advisers conducting an initial copyright-risk review.
Not ideal for
It is not a substitute for jurisdiction-specific legal advice or forensic musicology in active litigation.
From the transcript
“one thing that you you really cannot copyright is harmonic sequences because you can go back to the Renaissance and find chord sequences that are…”
“It's like trying to copyright grammar.”
“there are certain generic sequences that are built into music making, and at some point if you start to to make those copyrightable, then you…”
