LESSON IV.
ACTION OF SQUARE AND GRAND PIANOS.
Action of the Square Piano.
Up to about the year 1870, the square was the popular piano. The grand has always been too expensive for the great music-loving masses, and previous to this time the upright had not been developed sufficiently to assert itself as a satisfactory instrument. The numerous objections to the square piano forced its manufacture to be discontinued a few years after the introduction of the improved new upright. Square pianos that come, at the present day, under the hand of the tuner, are usually at least fifteen years old, and more frequently twenty or more. However, in some localities the tuner will meet numbers of these pianos and he will find them a great source of revenue, as they are almost invariably in need of repair.
