COMMUNICATING WITH THE PIANO TECHNICIAN

1. Myths and FAQs
    What makes a piano go out of tune?
    How often should a piano be tuned?
    Is electronic tuning OK? Is aural tuning OK?
    How do I clean the piano and how do I clean under the strings?
    What do I use to clean the keytops?
    How do I take care of the finish?
    “Pianos cannot be put against an outside wall”
    “You need to play the piano to keep it in tune”
    Playing on a “bad” or “heavy” piano as a practice technique
    Does learning about the technical aspects of the piano get in the way of playing it?
   
2. Useful Words
    Blurbling
    Blocking
   
3. Conventions:
    Naming notes – A0 through C8
    “Bass section” means that section of piano strings that contact bass bridge (but sometimes refers
      to all wrapped strings) but does not refer to the bass clef
   
4. Just because a piano has a problem doesn’t mean the piano is a bad piano.
5. “Is there any section of this piano that you do like?”
6. Interplay, interweaving of pianists’ perception – tone-predominant or touch-predominant?
7. Concert logistics and scheduling with your technician.
8. Technician’s job is to help you feel more comfortable with your instrument so you can focus on
    the music. The piano “disappears”, and all that is left is the music.
