Cluster 3: Florentine Independence & The First "Silent" Career
Leonardo life-system node from research dossier
Content Summary
Leonardo’s first career was as a musical celebrity and virtuoso of the lira da braccio. His independence was disrupted by the 1476 "Saltarelli" anonymous sodomy accusation, which reinforced a habit of secrecy and mirror writing.
Context Notes
The lira da braccio featured a flat bridge for chordal recitation. 2020 reconstructions by Fabio Chiari utilized equine skull resonance boxes, hypothesized by Leonardo to produce sonorous courtly tones. He linked musical "harmonic proportionality" to human anatomical intervals.
