The schematic file can be read using McEdit. If you dont have access to it, you can just rebuild the circuit yourself. Since the scope of the build is only the first few 8 measures of the song, its probably pretty reasonable to just rebuild it.

The spreadsheet screen capture shows the delays and note block values to allow you to build it yourself. To build it yourself, you can place a sequence of alternating redstone and delay elements. You can attach notes to the redstone and set the note values with the values in the "note 1 click count" column. You would set the note value by right clicking the note block the number of times in the "note 1 click count" column.

The delay circuit following each note would have the setting listed in the "post note delay" column. Note that each delay element can only be set to values 1-4, so you would need to put several in line and add up their delay values to get the numbers larger than 4. (for example, to get 6, use two delays back to back with settings of 3 and 3, or 2 and 4).
