<strong>Music</strong> Perception 21<br />

2001a). Janata <strong>and</strong> Grafton (2003) run a meta-analysis on bra<strong>in</strong> imag<strong>in</strong>g studies on<br />

sequence learn<strong>in</strong>g <strong>and</strong> time-<strong>in</strong>terval production <strong>in</strong> order to disentangle the <strong>in</strong>fluence <strong>of</strong><br />

temporal (e.g., rhythmical complexity) <strong>and</strong> ord<strong>in</strong>al complexity (e.g., complexity <strong>of</strong><br />

f<strong>in</strong>ger movements). They found anterior c<strong>in</strong>gulate, <strong>in</strong>sula, <strong>and</strong> precuneus <strong>in</strong>fluenced by<br />

ord<strong>in</strong>al complexity (with rather less temporal complexity) while the <strong>in</strong>traparietal sulcus<br />

was merely responsive to temporal complexity. When both temporal <strong>and</strong> ord<strong>in</strong>al complexity<br />

was <strong>in</strong>creased, ventrolateral prefrontal cortex, basal ganglia, <strong>and</strong> thalamus are<br />

most sensitive.<br />

In subsequent stages, structural reanalysis <strong>and</strong> repair may be necessary. Electro-<br />

physiologically, these processes may be reflected <strong>in</strong> the ERPs as positive potentials that<br />

are maximal around 600–900 ms. Besson <strong>and</strong> Faïta (1995) found a larger LPC (late<br />

positive component) <strong>in</strong> response to different violations <strong>of</strong> expectancies (an <strong>in</strong>congruous<br />

note that was either diatonic, non-diatonic, or a change <strong>in</strong> rhythm). Moreover, they<br />

found that both, the tonal structure <strong>and</strong> the familiarity with the musical pieces, may<br />

modulate the amplitude <strong>and</strong> the latency <strong>of</strong> the LPC. A comparable ERP component was<br />

found by Patel et al. (1998).<br />

Both, mean<strong>in</strong>g <strong>and</strong> emotion are assumed to <strong>in</strong>teract with processes <strong>of</strong> structure build-<br />

<strong>in</strong>g (<strong>in</strong>dicated by the thick l<strong>in</strong>es <strong>in</strong> the model <strong>of</strong> Koelsch & Siebel, 2005). The emergence<br />

<strong>of</strong> mean<strong>in</strong>g, based on the process<strong>in</strong>g <strong>of</strong> musical structure, requires <strong>in</strong>tegration <strong>of</strong><br />

expected <strong>and</strong> unexpected events <strong>in</strong>to a larger, mean<strong>in</strong>gful musical context (Koelsch,<br />

2005; Koelsch et al., 2004).<br />

Experienc<strong>in</strong>g music is <strong>in</strong>timately related to its emotional appeal (Jusl<strong>in</strong> & Sloboda,<br />

2001). For example, adult members <strong>of</strong> a culture mostly agree on the emotional characterization<br />

<strong>of</strong> a musical piece <strong>and</strong> tend to select the same adjectives to describe it<br />

(Hevner, 1936). The outcome <strong>of</strong> syntactic process<strong>in</strong>g may be important for process<strong>in</strong>g<br />

mean<strong>in</strong>g <strong>and</strong> emotion <strong>in</strong> music: Mechanisms for represent<strong>in</strong>g music are multidimensional<br />

<strong>and</strong> hierarchical. <strong>Music</strong> is, thus, characterized by po<strong>in</strong>ts <strong>of</strong> greater or lesser<br />

prom<strong>in</strong>ence or distance from one another. The emotion <strong>in</strong>duced by music is strongly<br />

affected by the modulation <strong>of</strong> tension <strong>and</strong> resolution with<strong>in</strong> a piece. It appears to be a<br />

function <strong>of</strong> cognitive representations <strong>of</strong> tonality (Krumhansl, 1990; Lerdahl, 2001; L. B.<br />

Meyer, 1956; Narmour, 1990). Expression <strong>in</strong> music is one means to make these structural<br />

features more prom<strong>in</strong>ent thus heighten<strong>in</strong>g the emotional response. Studies <strong>in</strong>vestigat<strong>in</strong>g<br />

the bra<strong>in</strong> correlates <strong>of</strong> emotion elicited by music (Blood & Zatorre, 2001; Blood,<br />

Zatorre, Bermudez, & Evans, 1999; Menon & Levit<strong>in</strong>, 2005) found activity <strong>in</strong> some<br />

bra<strong>in</strong> regions <strong>in</strong> the orbit<strong>of</strong>rontal cortex, regarded as <strong>in</strong>terface between cognition <strong>and</strong>
