test blows

[Daniel Schreffler]

It seems that so far eveyone uses the same technique for all pianos , but I
know this is not so .It seems to change from piano to piano , maybe from pin
to pin. I've checked it out  with Sat111.Slame the note with a good stong
blow and watch the lights go spinning to the left. Even with out the hammer
on the pin.Spongy pin ? Maybe . Other pianos  , a good blow, slight wiggle
of the hammer on the pin  rock steady-.
