The impact of the radio in the 1930s can be compared to the force of change in people's lives today caused by current technology. Marguerite V. Hood (1903-92), a recognized leader in the music education profession during the 1930s, understood the importance of music education radio broadcasts for rural one-room schools and music education classes. In 1936, she began a series of broadcasts in an effort to reach all children in Montana and was appointed radio director for the KGVO "Montana School of the Air" program. Hood recognized the necessity of using contemporary resources in music education, a need that exists today. Music educators who offer learning experiences encompassing various music listening activities and musical styles through all types of media provide students with a rich, fertile environment for cultivating the understanding and appreciation of all music genres.
