Classical MIDI

What It Is

Real MIDI files --- Bach (chorale, Brandenburg 3), Beethoven (5th), Mozart (Figaro). Raw Standard MIDI format 1 bytes: delta-time VLQs, note-on/off events, multi-track. 365KB.

Interpretation

Standard analysis sees: left-skewed; anti-correlated (alternating); blue spectrum (high-frequency power); time-irreversible (sharp rises, slow decay). The atlas finds no named structure, but the source is distinctively extreme on Attractor Reconstruction:lyap_sum (-3.7z) — beyond what the standard bank predicts for it. It sits beside Chirikov Standard Map in the atlas (standard-bank rank 49) — a neighbor conventional features miss.
