Sheet Music—Scorch Plugin
Important note for Mozilla browsers: when installing the plugin, select the Manually Choose Browser Directory option on the first page.
Now, with the plugin installed, you can see the sheet music, such as The Evening Light, and even play and print the song. The Scorch page at Sibelius tells how to use the features of the sheet music plugin.
There are a couple extra settings available just above the sheet music: zoom and notehead type. In order for these to work, you will need to have cookies enabled for your browser. The site will remember the last settings you picked, and keep them for whatever score you view.
