Hi, Wim, rather than trying to limit pianistic creativity (how ever =
mundane and tawdry) I would consider this another opportunity to do work =
and execute the necessary repairs.=20

  Yesterday there was a note on the piano of one of the piano profs' D, =
("key rubs when holding down Db6 and playing C5)  Upon inspection, I =

  His response was:

  Wim,

  "I rarely play glissandos."


  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.=20

  His other comment was:

  "Perhaps the technicians guild needs to take this matter up with the=20
  composers guild, particularly the branch that deals with dead=20
  composers.  Debussy and Ravel were noted for their transgressions into =

  glissandi."


  Any takers for an ad hoc committee to investigate this problem and =
make recommendations?
