1. From Midi to Traditional Musical Notation by Emilios Cambouropoulos

2. Outline Introduction The Algorithm  Salience of Musical Objects  Beat Induction  Beat Tracking  Time Quantization Onset Quantization Duration Quantization  Pitch Spelling

3. Salience of Musical Objects Elementary Musical Objects are identified  Chords, arpeggiated chords, trills, mordents  Synchronization 40ms< onset < 70ms

4. Salience of Musical Objects contd… Musical Accent Beat Processing Application  More salient musical events have more influence over beat

5. Beat Induction and Beat Tracking A: event onsets B: accent of musical events Next beat = average of last three beats. -Disregard if salience is low May shift because low accent notes appear in onsets.

6. Onset and Duration Quantization

7. Pitch Spelling Refer to Cambouropoulos, 2000  Notational parsimony  Diatonic interval optimization  Tested in 3 complete Mozart sonatas (97% accuracy)

8. Conclusion The whole algorithm is tested in 13 complete Mozart sonatas  may add extra beats  may shift because of weak notes  module avoids rests and hardly depended on the streaming accuracy Overall : Encouraging Results !!!
