What do you like about this subject?

Mostly, after 48 years...I just like helping the consumer. Remember, there is no such thing as a "factory authorized" technician, and just belonging to the Piano Technicians Guild means nothing. One has to be REGISTERED to be qualified. Care should be taken in choosing a technician.

What do you still hope to achieve/learn in this field?

I would love for technicians in the field of piano technology,to be licensed in the state in which they intend to do business. I would like to see all technicians taking money for work perfomed, to be tested. This protects the consumer. I would also like to see a Piano Rebuilders' Contest just like juried contests for artists and performers and furniture makers.

Something interesting about this subject that others may not know:

The Piano Technicians Guild is an international organization that offers the opportunity for an individual to become qualified. Of the two classes of working technicians, only the Registered technician is tested and qualified. The Associate member can be a hobbyist, student, apprentice, piano mover, piano refinisher, etc.

Something controversial or provocative about this subject

Not all piano technicians are qualified...unfortunately. However, registered technicians from the Piano Technicians Guild must agree to a code of ethics, and this is monitored by the guild. Getting tested is a good thing. After all...how can we qualify our skills without testing. Plumbers, Doctors, Lawyers, Accountants and such all get tested. Why not piano techncians? What do they have to hide?

Hi Thomas:    The piano was made in 1911.    I wouldn't start out with throw away. Instead, I would put it on EBAY or Craigslist for 150.00 AS IS!    And, stipulate that the piano goes with NO warranty
