124 Stefan Koelsch Figure 2: (a) Data from the experiments by Daltrozzo & Schön (2009a), the left panel shows ERPs elicited by target words (primed by short musical excerpts), the right panel shows ERPs elicited by musical excerpts (primed by target words). The thick line represents ERPs elicited by unrelated stimuli, the thin line represents ERPs eli-cited by related stimuli. Note that the difference in N1 and P2 components is due to the fact that words were presented visually, and musical excerpts auditorily. Both meaningfully unrelated words and meaningfully unrelated musical excerpts elicited N400 potentials. (b) Chord sequences used in the experiment by Koelsch at al. (2000) the left sequence ends on a regular tonic chord, the right sequence ends on an ir–
