Tuning with a fork and the Sanderson Baldassin procedure.

Hi Alan,

Listen to f3 a3. Tap your knee on the fourth beat. Do that for three sets
of four beats. Then play a3 c#4 while keeping the tapping going at the same
speed. Count how many beats you hear. If it is five then it is a four to
five ratio. If it is slower then adjust c#4 until it is five.
