1. Go to the apple menu.
2. Go to "Control Panels".
3. Go to "Extensions Manager".
4. Go to the help menu and select "Show Balloons".
6. Scroll down to the extension labeled "QuicktimeTM Musical Instruments".
7. Move your mouse over it and it will show you three dictionary definitions of the word 'music'.
