An instrument is added for each sound of the note block. They can play different notes depending on what angle you are looking when you play it (looking up plays a higher pitch, looking lower plays a lower one).
You can also find rare spell sheets in dungeon chests. To play them, place your instrument in your offhand, and right click the sheet. When the tune is complete the spell will be cast. Modpack makers can tweak or disable these sheets' melodies and spells.
Custom tunes can be written by renaming a Blank Sheet with the ♪ character at the beginning (hold Alt and type 13 and release to type this). Any notes (abcdefgABCDEFG) in the name will be played in order. Spaces will skip a note.
