David, Mark, I'll have to say that I believe on the contrary that the main problem I noticed with the EDT is that you tend to forget that the pitch is possibly changing during your tuning time. There an aural tuner will get a more accepteable result while someone who rely (too much) on an EDT can get caught with a temperature change during the tuning. (indeed I tune unisons as I go so the tuning time is different from a one string method) I actually tune for a Jazz festival outdoor, and the last pitch raise from the dry indoor conditions (was 38% HR)to the somehow cold and humid outdoor yesterday was almost 2hz change (the piano ending at 444 Hz at the break. Knowing it will anyway go down during the day I did not over corrected , and the yesterday concert was done at 443. Today it is sunny and warm, and the piano will be back at its usual pitch 442. Mark I believe you should try to understand what moved and in what direction, go fast thru the correction, and twice, make a sold tuning and wait just before the concert for the final corrections. If time is short, do the best you can without disturbing the instrument too much from it's "natural" tuning, as you will have it back home after the concert Good luck Isaac Oleg -----Message d'origine----- De : pianotech-bounces@ptg.org [mailto:pianotech-bounces@ptg.org]De la part de David Ilvedson Envoyé : dimanche 20 juin 2004 06:14 À : pianotech@ptg.org Objet : RE: outside tuning on July 4--hopefully without fireworks Mark, If you are an accomplished aural tuner, then it is time to add a EDT to tool kit. Use it like the tool it is and it will improve your work. For the task at hand: I'd have the piano moved to the outdoor stage well before the performance. Make sure it is covered LOOSELY...i.e. lots of air flow, mainly to keep the sun off the piano. If it is a covered stage, keep in mind where the sun will sneak through. A few hours before the performance, I'd run through the tuning with my SAT III to rough it in. If it really went sharp, I'd go through it a couple of times. THERE IS NO SENSE IN TRYING TO FINE TUNE THE PIANO BY EAR IF YOU HAVE A CHANGE OF 3 CENTS OR MORE. Sorry for shouting...it's just a waste of your time and energy. Rough tune for an hour and fine tune for how ever long it takes you...personally, I fine tune with the machine. It will tell you immediately if something is changing. Finally: Just before the performance, touch up the unisons and go enjoy the concert.
