The right answer is, of course, ‘don’t know’.
In the U.S. one can attend piano tech courses at tertiary level. Here’s one that ‘Kenny’ from PW is attending right now. And these are the course descriptions. I wonder how many techs in Singapore can get a passing grade on the exams.
In the U.S. piano techs can become members of the Piano Technicians Guild after passing the PTG exam. Again, I wonder how many techs in Singapore can pass the PTG exams.
For those who don’t know, a guild is an association of craftsmen whose members are certified to be competent in their craft. Of course, not all PTG members are equally good, but at least if you engage a PTG member you have a good chance of getting a competent tech to work on your piano. Of course, there really isn’t a huge demand for techs in Singapore who can rebuild a piano, but you know what I’m getting at. 😉
