[pianotech] Tuning contest proposal

[David Ilvedson]

Coleman and Devebaugh (spelling) did classes for years showing that ETD and Aural could do the same thing...once again:  PTG classes at conventions...

My recollection is that Jim Coleman was one of the tuners, and used the ETD. I don't recall the other one.

This "test" has been done! I can't remember exactly when or who was invloved, but I do know that they were both well know and respected tuners. The result? Experienced tuners could not tell definitively which was aural and which was etd!

Since there are many and heated views of which tuning way is better ....



I propose a tuning contest and final report.



Rules:

- Find an independent person or team to officiate

- Provide two identical piano and settings

- Two highly respected tuners that are proficient in there respective skills (Aural and ETD)

- Tune each piano at A440 - Equal Temperament

- One tune aurally

- One tune with ETD

- Repeat (with the same tuners) for each Brand, Size and Style of piano



Results:

- Using an independent way to determine accuracy of the pitch of each note (all 88 notes) (Tuning forks / ETD in "test" mode" / etc)

- If ETD is used, the initial one for the tuning can not be used.

- Obviously, this rules out the tuning stability (how long the piano stays in tune), hammer technique, etc. (All the human elements that can't be accurately measured)



Extra idea:

- Repeat contest with each commercial ETD.



Eagerly waiting the results,

Duaine
