MP3:
When you click an MP3 link, an application (such as QuickTime) might play it in your browser. Sometimes this doesn't work. If you'd like to download the MP3 before playing it, right click the link to get a popup window. If using Internet Explorer, choose "Save Target As...", or if using Firefox, choose "Save Link As...".

Watch and Listen (Scorch):

Download the Scorch Plugin (Windows/Mac) from Sibelius to watch the music play (lousy midi sound though).

Sheet music & Comments (PDF):

The sheet music and comments are available in PDF (Portable Document Format). To view PDF documents, you need to install the Acrobat Reader program.

Scans of original hand written sheet music (GIF):
The sheet music originals and art scans are usually at 150 dpi. Old versions of Internet Explore display them at 72 dpi, so they're around twice the desired size, while newer versions will size it to the open browser window. The Mozilla browser will display it sized to the window, but also give you a magnifying glass for the cursor. Click once to enlarge, and a second time to size it back to the Mozilla window.
