But you do have to be able to hear when fourths and fifths are wider or narrower than beatless. I never use the ETD for pitch raising -- too much fuss. I just set my A4 to 25 - 50 % higher than the amount the piano is flat (a separate discussion about which I had a post a few weeks ago), then set a quick temperament using 4ths and 5ths only, then quickly tune octaves up to the top, just listening for pure or slightly stretched octaves (depending how flat the treble is), then bring in all the unisons (order unimportant in my opinion if it's a big pitch raise -- it's going to drift out some, anyhow), then the bass -- octaves quickly down to the bottom, just listening for beatless octaves, not bothering with more sophisticated checks, then the unisons. Takes 15 - 20 minutes. Then I start over and fine tune, usually with the ETD but I don't have to have it, and sometimes I leave it behind on purpose, just to keep in practice tuning by ear. --David Nereson, RPT
