On almost all computers, samples are automatically available when you click on "Listen To Audio Sample" or "View Sheet Music Sample".
.MP3 For .mp3's a screen appears from which the sound automatically starts playing.
.PDF .pdf's appear on the screen in the default application that opens .pdf's on that computer.
RIGHT CLICK If your computer doesn't immediately open samples, try right clicking (control-click for Mac users with a one-button mouse) on "Listen To Audio Sample" or "View Sheet Music Sample". From the menu that appears when you right click, save the sample to your hard drive and then open it from there.
ASK for SUPPORT If this doesn't work easily, please send an email to firstname.lastname@example.org.
