To use Musical Explorers Around the World students simply have to click on one of the large placemarks on the map. When clicked, each placemark reveals a musician or two from that place, the music they make, and the instruments they use. Each placemark contains a video featuring the musicians explaining a little bit about themselves and their music. Each of the placemarks on the map also contains audio files to listen to full songs performed by the musicians on the map.
Musical Explorers Around the World is part of a larger collection of instructional resources hosted by Carnegie Hall for music teachers. Each of the placemarks in the map contains links to lesson plans that are appropriate for introducing elementary school students to terminology and concepts like rhythm, harmony, and melody.
I think that Musical Explorers Around the World could be a great resource to have students explore on their own or as part of a group activity in which they investigate questions about why instruments and music develop and are different based on geography.
