Summary

The analysis compares melodic contours, harmonic progressions, rhythmic patterns, and structural layout between the client and reference tracks. Scores below are normalized to a 0–100 scale.

Methodology

The system performs deterministic feature extraction and similarity scoring:

• Fingerprint pre-filter on robust audio hashes to narrow the comparison set.
• Melody: pitch tracking, interval sequence extraction, and transposition-invariant sequence alignment.
• Harmony: chroma features, chord estimation, and functional harmony (I, IV, V, vi, etc.) similarity.
• Rhythm: onset detection, tempo estimation, and beat-synchronous pattern comparison.
• Structure: detection of intro/verse/chorus/bridge and alignment of section order and repetition.

Limitations & legal positioning

This report is an analytical summary, not a legal verdict. Common genre clichés (e.g., I–V–vi–IV progressions or stock rhythmic patterns) are down-weighted where possible, but cannot be fully eliminated. Results are reproducible given the same inputs and settings. Final decisions regarding infringement should be made by qualified legal professionals.
