August 10, 2012 by Eric

I’ve been told that I must have a good ear, usually by someone I’ve just met who has learned that I’m a piano technician, and I’ve always wondered exactly what it meant. Piano tuners do train themselves to hear components of piano tone, usually called partials or harmonics. These are pitches within pitches (the g […]
