YES YES YES was NO NO NO

[David Ilvedson]

I think I already mentioned when I was in training we spent 3 months of nothing but unison tuning (1 hour a day)...theory in the classroom but hands on unisons...

>Hi Ric,

>> "Setting the Fundamental pitch:
>> 1. Comare the note A37 to the tone of the tuning fork, and manipulate 
>> the tuning hammer to produce a no beat condition as in unison tuning. 
>> The tone A 37 is correctly tuned if the rate of the beats produced by 
>> the two tuning forks of 440 and 442, and that of the beats 
>> produced by 
>> the note A37 and the tuning fork of 442 are the same.
>> 
>> 2: Set the pitch of A37 using the tuning fork in the same way as 
>> described in method 1. Check to see whether the rate of beats 
>> produced 
>> by the major 3rd (A37 and F33) and that of the beats produced by the 
>> tuning fork and the note F33 are the same. In another way the 
>> note A37 
>> can be tuned later by setting the beat rate of A37 and F33 to that of 
>> the tuning fork and F33
>> 
>> 3: Adjust the beats produced by the tuning fork and the note D30 to a 
>> comfortable speed (3-4 beats/second). Tune A37 so that the 
>> beat speed of 
>> the tuning fork and D30 is the same as the fifth A37-D30, and 
>> a beatless 
>> condition is achieved between the tuning fork and A37. An 
>> octave of A49 
>> can be used instead of D30."
