One of my most beloved possessions is a chromatic pitch pipe. It belonged to my Finnish grandfather, a luthier, a fine woodworker, and a beautiful singer.
Its purpose is to set a pitch to tune an instrument or to sing a melody; I use it when I play my guitar (my grandfather made that guitar, another beloved thing). The design is constructed on the chromatic circle, one of those mathematical, musical patterns I appreciate very much. It is in fact a basic harmonica, descended from the 18th century pitch pipe, which could be used in place of a tuning fork.
The other side. Isn’t it charming? I love its simplicity and clean typographic design. You can still find these new. Do you know, I’d quite forgotten, I met a piano tuner the other day and learned a couple of things - I’ll show you soon.
