37 steps

[Barbara Richmond]

Re: 37 stepsI've been to the Little Red School House (1986).  They taught regulating in cycles.  Just listing these "steps" doesn't tell you the whole story.  Besides tightening the screws, I was taught <there> that the three things you need before you start to regulate in earnest is blow distance, some drop and and the repetition springs need enough strength to make the hammers rise when released slowly out of check.  Sometimes it takes a little work to get to that point!  LaRoy Edwards is soft spoken, but has a wonderful sense of humor.  The information he's shared (and I was willing to listen to) is largely why I've been a successful technician.

  I concur. Actually, Potter (The Randy Potter School of Witchcraft and Piano Technology) does nicely stress the importance of, how shall we say, cyclical adjustments, i.e., going back to previous steps at certain points. Don Mannino, Roger Jolly (where's he been lately?), and others also stress this in their classes.

  I don't know about Potter or Reblitz, but if you regulate according to the Yamaha 37 steps you'll have some problems. Spring strength affects almost every other regulation point; if you don't do it very precisely first, and then refine it later on, thing will change, and not for the better; wrong spring strength (too little or too much) will blur and confuse the feeling of the other precise regulation protocols.


  Blow distance, some aftertouch, then spring strength. Foist and fawmost, kiddies. Balance is the key.
