    "ruthRecording": "Theme follows the lead sheet; accompaniment is our arrangement. Fixed-tempo phrasing and bass gestures do not reproduce the recording.",
    "spanishRecording": "Same-pitch Bb3 comparison: approximately 233.93 Hz in Ruth, 233.68 Hz in Spanish, 233.30 Hz in synthesis. This single-note comparison cannot establish open-string tuning.",
    "instrumentLimits": "An isolated G3 in the current guitar model shifts from near 196 Hz toward 197.7 Hz as its fundamental decays. Coupled-body tuning/decay remains a model limitation, not a between-song retuning explanation. Chord notes still use separate body voices."
