Music practice since childhood affects the development of hearing skills. An important classification in Western music is the chords’ major‐minor dichotomy. Its preattentive auditory discrimination was studied here using a mismatch negativity ( MMN ) paradigm in 13‐year‐olds with active hobbies, music‐related (music group) or other (control group). In a context of root major chords, root minor chords and inverted major chords were presented infrequently. The interval structure of inverted majors differs more from root majors than the interval structure of root minors. However, the identity of the chords is the same in inverted and root majors (major), but different in root minors. The deviant chords introduced no new frequencies to the paradigm. Hence, an MMN caused by physical deviance was prevented. An MMN was elicited by the minor chords but not by the inverted majors. The MMN amplitude in the music group was larger than in the control group. Thus, the conceptual discrimination skills are present already in the preattentive processing level of the auditory cortex, and musical training can advance these skills.
