I wrote the following to the= professor. </DIV> <DIV> </DIV> <DIV><BR> <BR>> The problem with the keys you pointed out= was the Dd back check was<BR>> rubbing  <BR>> against= the C back check, but only when the Db was depressed. When= I<BR>> had the  <BR>> action out, I noticed several= other back checks that were almost<BR>> rubbing <BR>>= against  their neighbors. There was one similarity with all= the ones<BR>> that were <BR>> close to  their= neighbors. They all belonged to a black key. Then I<BR>>= looked at the <BR>> front of  the key, and noticed they= were very close to the white key.<BR>> <BR>> = <BR>> This is caused by playing glissandos on the black keys.= It has always<BR>> been  <BR>> advised for piano= players not to play glissando on the black keys.<BR>>= Primarily  <BR>> because the key button can't take the= strain, but also because it<BR>> does cause <BR>>= the  key to move over, and thus create this problem.= <BR>>  <BR>> Now, if you are not playing glissando on= the black key, I wonder if<BR>> perhaps  <BR>> when= you play a glissando on the white key, your fingers rub against= <BR>> the <BR>> black keys, causing them to move over.= <BR>>  <BR></DIV> <DIV>His response was:</DIV> <DIV> </DIV> <DIV>Wim,<BR><BR>"I rarely play glissandos."<BR></DIV> <DIV> </DIV> <DIV>My question to you guys is this. Have any of you experienced= this, and what solution do you have? This is a 45 year old D,= with the original action. </DIV> <DIV> </DIV> <DIV>His other comment was:</DIV> <DIV> </DIV> <DIV>"Perhaps the technicians guild needs to take this matter up= with the <BR>composers guild, particularly the branch that deals= with dead <BR>composers.  Debussy and Ravel were noted for= their transgressions into <BR>glissandi."<BR><BR></DIV> <DIV>Any takers for an ad hoc committee to investigate this= problem and make recommendations?<IMG= src="http://cdn-cf.aol.com/se/smi/0201d20638/02"></DIV> <DIV> </DIV> <DIV> </DIV> <DIV>Wim</DIV> <DIV><FONT lang=0 face=Arial size=2 PTSIZE="10"= FAMILY="SANSSERIF">Willem Blees, RPT<BR>Piano= Tuner/Technician<BR>School of Music<BR>University of= Alabama<BR>Tuscaloosa, AL= USA</FONT></DIV></FONT></DIV></BODY></HTML>
