Certified Piano Tuner (CPT): what does that mean?
The Dutch association for piano technicians (VvPN) has created a tuning exam to test the level of piano tuners. The piano tuner needs to tune a grand piano to the best of his/her ability within a set time limit. The result is recorded with a sophisticated tuning machine and then compared to a reference tuning. This reference tuning has been created and optimized by highly experienced piano tuners. The time result and comparison are used to generate a score, giving the applicant a ‘pass’ or ‘fail’ on the exam.
I am proud to count myself among the prestigious ranks of CPTers.
