As "Music Educators Journal" celebrates its centennial, it is appropriate to look back over the past century to see how advocacy in music education has evolved. Of the more than 200 submitted articles on advocacy, four main themes emerged: music education in community, the relevancy of music education, the value of music education, and the perpetual nature of advocacy. These themes were presented in the context of previous articles and then blended to create a platform from which current practitioners can work to promote music instruction in schools.
