Abridged Summary: This study “investigated the ERP correlates of the influence of tonal expectations on pitch processing. Participants performed a pitch discrimination task between penultimate and final tones of melodies. These last two tones were a repetition of the same musical note, but penultimate tones were always in tune whereas final tones were slightly out of tune in half of the trials…Manipulating tonal expectations with minimal acoustic changes allowed us to focus on the cognitive expectations on the basis of the listeners’ knowledge of tonal structures. ..Our results suggest that cognitive tonal expectations can influence pitch perception at several steps of processing, starting with early attentional selection of pitch.”
