Harmonic Similarity
Harmonic Similarity compares musical material and scores how closely it matches — useful when you’re writing and that hook feels suspiciously familiar.
How to use it
- Give the tool the two pieces of material to compare.
- Review the similarity analysis — it looks at the harmonic content, not just surface notes.
- Use the result as a songwriting sanity check before you fall in love with a progression.
Honest limits
This is a writing aid, not legal advice. Copyright disputes involve far more than harmonic similarity (melody, rhythm, lyrics, access, jurisdiction). If real money is on the line, talk to a music-rights attorney.
