Notes, also known as Musical Notes, are items in the Banjo-Kazooie franchise. They are usually used to pay for moves that Banjo and Kazooie can use in the games the notes appear in, and in Nuts & Bolts, they can be used to pay for vehicle blueprints, vehicle parts, and other such things. However, in the very first game of the series, Banjo-Kazooie, Banjo and Kazooie collected notes to open Note Doors, which led to new areas of Gruntilda's Lair. In Banjo-Tooie, musical notes (including the treble clef worth 20 notes) can be collected in nests. Originally, they were all gold, but in Nuts & Bolts, the notes were of differing metals, and the metals were bronze, silver, and gold, in order of value.
