How to tune Pure Tuning

Two recipes describing how to tune Pure Tuning by ear can be viewed here. German translation is here. You may need a tuner to tune Pure Tuning to norm A4 = 440 Hz.

Beating rates

Beating rates for each interval between double pedal (contra) C and treble (two-line) C can be viewed here. Recalculation for A = 440 Hz is here. Thanks to Bradley Lehman for providing sheet that I use for calculations.
