Présentation de l'éditeur
For some years past a lack of competent men in the profession of Piano Tuning has been generally acknowledged. This may be accounted for as follows: The immense popularity of the piano and the assiduous efforts of factories and salesmen have led to the result that nearly every well-to-do household is furnished with an instrument. To supply this demand the annual production and sale for the year 1906 is estimated at three hundred thousand pianos in the United States.
