JMI initially focused on presenting "good music" (classical music) to young audiences through concerts in the main concert halls and later through school concerts. The focus changed over time to also encompass young musicians through music camps, competitions and youth orchestras.
In the late 60's, JMI began to open up to other styles of music such as contemporary classical music, ethnic and traditional music, jazz, pop and rock. In doing so JMI became an international platform for youth and music worldwide, enabling young people to develop through music across all boundaries.
