Dear friends of Pianoconcerto,
I have found a website, which is this www.pianotechacademy.com, that offers the possibility to those interested to enroll in and attend a course for piano tuning technicians and not only that, but everything that revolves around the fine-tuning of the instrument.
I believe I have done something pleasant for those like myself who are "in love" with this wonderful instrument.
greetings
saverio
