Musical Spokes: Checking and Adjusting Spokes Manually (without spoke torque wrench)

This is the old school method of checking and adjusting spoke tension without having to use a special spoke torque wrench. Do this after every other ride or so as part of your bike's regular checkup.
Will you know the exact torque on each spoke? No.
Do you think you'd be faster if you did? Nope!
This method works great just for keeping the spokes relatively balanced. You should pull the wheel off the bike and put it into a truing stand to make adjustments to correct runout as needed.
