I thought of posting this in the “Regarding C4 E4 M3 in Bremmer EBVT III “ post, but thought is would be best to start this on a fresh thread.
I thought a little about the problem that Mr. Bremmer posted on using an ETD for tuning a Well Temperament. Here is my solution,(only used once, I tune ET 95% of the time):
It has beeen stated that an aural tuner will naturally stretch an UT at the extremities of the piano so that the high treble and low bass will be nearly the same as ET. So, I made a set of 3 UT's for Tunelab.
First there is EBVT III, full strength. This is the same as what Bill Bremmer has posted.
Second, EBVT III at 2/3 strength. The first offsets are all multiplied by 2/3 and saved as a new temperament.
Third, EBVT III at 1/3 strength. The first offsets are all multiplied by 1/3 and saved as a new temperament.
Here's how it works:
Tune A0-A1 in ET.
Tune A1 to A2 at EBVT III at 1/3 strength.
Tune A2-A3 at EBVT III 2/3 Strength
Tune A3-A4 with full EBVT III
A4-A5, EBVT III 2/3 strength
A5-A6 EBVT III 1/3 Strength
A6-C8 in ET
Each octave (except the A6-A7 to C7-C8 octaves) will have a different amount of stretch. On an ETD, the offset for all the A’s will always be zero, so you have to change at every A.
What do you think?
My lone experiment was a small Wurlitzer Spinet, so it was tough to tell if some of those octaves in the bass were beating more than they would in ET. I will say, that when I was done, it was one of the best sounding spinets I’ve played, if that means anything.
