1.
Pull the high G-string through the first string groove in the bridge. Pull the string until the bead at the other end of the string comes in contact with the back of the bridge.
2.
Thread the upper end of the high G-string through the hole in the tuner pin located on the neck of the banana at the fifth edge. Pull the string until there is only a slight slack between the bridge and the tuner.
3.
Wrap the end of the string counterclockwise around the tuner’s stick and over the string running from the bridge. Then pull the string underneath, creating a simple knot.
4.
Pull the end of the string until the knot is tight around the tuner.
5.
Turn the tuner pin to tighten and set up the string. Use an electronic tuner, pitch beep or software tuner on your computer to set the string to a high G-tone.
6.
Thread the low D-string through the other string in the bridge. Pull string until the bead at the bottom end comes in contact with the bridge.
7.
Thread the low D-string through the Hole on the first tuner pin on the main deck (the lower left stick as you look at the banjo upright). Repeat steps 2 to 5 with this and the rest of the strings, using the remaining bridge grooves and tuner pin in succession until you end up with the high D-string.
Tips and warnings
The five-string path is separated by high G, low D, low G, B and high D-strings. Banjo strings are usually made of wound steel or metal. The strings are attached to a bridge at the bottom of the instrument and run the length of the neck to the tuner sticks – four at the main shaft and a fifth for the high G-string that lies on the neck at the fifth edge.
