Allen This work is the result of an interdisciplinary collaboration between scientists from the fields of audio signal processing phonetics and cognitive neuroscience aiming at studying the perception of modifications in meter rhythm semantics and harmony in language and music. A special time-stretching algorithm was developed to work with natural speech. In the language part French sentences ending with tri-syllabic congruous or incongruous words metrically modified or not were made. In the music part short melodies made of triplets rhythmically and or harmonically modified were built. These stimuli were presented to a group of listeners that were asked to focus their attention either on meter rhythm or semantics harmony and to judge whether or not the sentences melodies were acceptable. Language ERP analyses indicate that semantically incongruous words are processed independently of the subject s attention thus arguing for automatic semantic processing. In addition metric incongruities seem to influence semantic processing. Music ERP analyses show that rhythmic incongruities are processed independently of attention revealing automatic processing of rhythm in music. .
