Such clear information. Nice job.

There is a piano technicians guild and they do have an exam process. You could also attend north bennet street school which has a good program for piano tuning and repair and there is also a university in Huston that has course work. Other than that its simply passed on knowledge. Most people mentor under a master technician for years and gradually get better and better until you feel comfortable to go into business. I also will disagree with the technician in the video. I often will show clients who ask as to how they can touch up their piano. Though that being said, a full tuning is something completely different than touching up a note or two. I have heard of some technicians who get nervous about teaching customers, but I find the task to be difficult enough to not warrant any worry. Also in regards to the steinways taking longer, that has a lot to do with where the tuning pin is in relation to the cutoff bar. Many steinways have this massive distance. In the high trebble sometimes the part of the string that doesn't make any noise is longer than the speaking length. This makes it incredibly hard to tune because of how much stretch the strings have behind the cutoff bar meaning you have to constantly go back and forth to equalize the tension between the two. There are some specialized techniques that can get you past this, but its still a bit of a pain even when you get good at it.

I'm looking into becoming a tuner fairly soon and this was incredibly insightful! Appreciate the video :)

Thank you for the video. I’m contemplating becoming a tuner/tech when I retire so this was very informative. Looking forward to part 2.

Damn it, I hate to say it, but I feel I’m being called to be a piano technician!
