(4)Concerning harmonic aspects of major-minor tonal music, Musical syntax can be characterized by statistical regularities in the succession of chord functions in time, that is probabilities of chord transitions. As these regularities are stored in a [[long-term memory]], predictions about following chords are made automatically, when listening to a musical phrase.
====MMN and ERAN====
The violation of these automatically made predictions lead to the observation of so-called [[Event-related potential|ERPs]] (event related potential, a stereotyped electrophysiological response to an internal or external stimulus). Two forms of ERPs can be detected in the context of processing music. One is the [[Mismatch negativity|MMN]] (mismatch negativity), which has first been investigated only with physical deviants like [[frequency]], [[sound intensity]], [[timbre]] deviants (referred to as [[phMMN]]) and could now also be shown for changes of abstract auditory features like tone pitches (referred to as [[afMMN]]). The other one is the so-called [[Electroencephalography|ERAN]] (early right anterior negativity), which can be elicited by syntactic irregularities in music. Both the ERAN and the MMN are ERPs indicating a mismatch between predictions based on regularities and actually experienced acoustic information. As for a long time it seemed to be, that the ERAN is a special variant of the MMN, the question arises, why they are told apart today. There are several differences between the MMN and the ERAN found in the last years:

(4)At least a comparison between the actually incoming sound and the predictions based on the model is made. This process is partly the same for the MMN and the ERAN as well.
=== Comparison of the processing of musical and linguistic syntax===
Source:<ref name=Patel2008/> As the ERAN is similar to an ERP called [[Early Left Anterior Negativity|ELAN]] which can be elicited by violation of linguistic syntax it seems to be obvious that the ERAN really represents syntactic processing. Deduced from this thought an interaction between music-syntactic and language-syntactic processing would be very likely.There are different possibilities in [[neuroscience]] to approach to an answer to the question of an overlap between the neuronal processing of linguistic and musical syntax.
