To install a bridge on a banjo, you should:
• Place the instrument on the flat surface and then slide the new bridge under the strings.
• Near the tailpiece, you should slightly lift the strings and make sure that the bridge is upright.
• Place each string into a corresponding slot.
• You should now slide the bridge toward the tailpiece, so it’s about two-thirds of the way from the instrument’s head.
• Now you can tune your banjo.
