tip: sometimes web browsers do not download PDF files smoothly. If you are having trouble downloading or viewing the sheet music with your browser, use your mouse (or mousepad) button on the right (instead of the left) and a little option menu will pop up; right-click on the "Download" link, then look for an option like "Save link as..." or "Download linked file as..." -- then save the file to somewhere convenient like your Desktop or Downloads folder. Then go to that folder, and you can then usually just click on it normally to open it using Adobe Reader or Preview or any other PDF file reader.

If you are using a mousepad on a Mac computer, you can simulate a right-click by pressing the "control" button while you click on the "Download" link.
