Donning flame suit now: ;-) If you use an ETD to set the bearings (like I do) aren't you putting your tooner ear at risk too? I do use the ETD to track what is going on as I spread out from the middle, but since I am using a stone-age ETD I trust my ear and correct the ETD settings constantly. Where I use it most is extreme treble where I and a lot of aural tuners have trouble hearing the really short beats. If your ETD doesn't deal with stretch as needed by the piano, you will encounter some really funny things happening in little pianos. In a spinet you can expect to come close to stretching the note on either side of A4. That is why a set of tuning forks for the octave temperament (they sell them at Schaff) does not work for all pianos. Of-course checking the Major Thirds (I do them as triads) will catch this problem, but then you are tuning twice. When you are tuning for institutions where the bell rings all too soon and the classroom is suddenly flooded with curious students, a good ETD is very helpful. I prepped a piano for a Liszt recital last week and it was a pitch-raise with a nasty killer octave. Next time I'll come prepared to level strings and drift the wires around pins on the bridge. Anyhow, I did the pitch raise with ear-plugs in and then spent a lot of time (I had the whole place to myself and no time constraints) tuning aurally with the tuner over there automatically following me around (an amusing distraction). For me, tuning aurally is a great pleasure not always afforded by the commercial circumstances I find myself in. A week later, lots of practise, and ten degrees warmer I volunteered to fix four unisons the day of the concert. That wasn't a call-back, when I asked the artist if it might need a little touch-up by now he wasn't certain but mentioned he was uncomfortable with something in D flat major in the bass. Unless you are tuning for a tuner you aren't likely to get a callback. I've tuned after some atrocious tunings (not here in Las Cruces fellow chapter members ;-) ). The customer only noticed that the previous tuning was bad by how wonderful my tuning was by comparison. Ducking into my foxhole now, ;-) Andrew Las Cruces, NM
