PSC 136 Lecture Notes - Lecture 13: Markov Chain, Schenkerian Analysis, Geodesic
Document Summary
The likelihood that a particular note or chord will follow another note or chord. Anchoring - a non - diatonic tone is very likely to be followed by a diatonic tone. Genres are even characterized by their transition probabilities. The thickness of the arrow indicates the probability of going from 1 chord to the next. The voltages are being generated by the synchronous activity of large populations of neurons. Responses to harmonic violations in non - musicians. Grand - average erps (averaged across subjects) in response to neapolitan (deviant) & in - key chords. Deviants elicit an early right - anterior negatively (eran), and a bilateral negativity (n5) It is suggested that the eran reflects a response to the violation of a tonal expectancy, & the n5 a tonal integration process. The technique used here is magnetoencephalography (meg) which is like eeg, but it measures magnetic fields instead & is therefore better for localizing sources of activity.
