Below is exactly what Yamaha's Little Red School house and all their seminars teach. Thank you Laroy Edwards...very informative and it is being taught...in piano tech schools? Probably not! David I. >> Actually it is amazingly simple and should be taught at all >> piano tech schools : >> >> We draw a curved line which represents the striking distance. >> It ends just before the string as let off takes place. >> Drop follows, and the up-going line goes down sharply for a >> very short while. >> At the end of this short line going down we draw a >> horizontal line : we have reached the bottom, which is the front >punching. >> A perfect after-touch should be a movement of about 0.4 mm >> when we press the key - gently - down into the punching. >Do you mean a hammer rise movement? I understood it as a movement of >the key after letoff. >I do that by feel, and if the aftertouch is 0.4 (at the key), the >hammer seems to move the same or a little less that the key (not >much). >What is the ratio between hammer rise and key movement after let off ? >I bet it is different from action to action, depending of the kind of >whippen, the position of the roller on the lever, >> Pianists often find this moment of after-touch the most important >one and three after-touch possibilities should be available to them : > 'Hard landing, neutral/medium landing, soft landing'. >> The tone is generous, strong enough and does not need a lot >> of needling. >> The 0,4 mm after-touch is standard. >> This may seem all too easy but, as a matter of fact, it is >> an art in itself. >> The more precise and sensitive we are, the finer the touch >> and the more subtle and rich the tone. >After saying that you can quit the show under the applause ! >In French :" Il ne reste plus qu'a tirer l'echelle ...." >Warms Regards from France. >Isaac OLEG >_______________________________________________ >pianotech list info: https://www.moypiano.com/resources/#archives
