In the last two decades, Spain's general music education curriculum has moved beyond the exaltation of so-called Western art music to also include some instances of non-Western musical traditions. This process of diversification is often articulated as entirely positive. The present paper interrogates such discourses, following a post-structural, socio-historical approach. It looks into the circumstances surrounding the emergence of Spain's multicultural music education as a field of study, paying special attention to the inherent limitations and (contradictory) effects it produced. It argues that, despite its progressive-sounding rhetoric, Spain's multicultural music education still draws on age-old colonial discourses that pin the Self and the Other against each other. Following this line of inquiry, the paper then unpacks the emergence of the notions of music and schooling, as well as Spain's recent move toward deregulating music and the arts as school subjects. Interspersed, the paper includes brief critical discourse analyses of policy documents and scholarly texts to exemplify its main points.
