learn to play, and to drop the wrists below the level of the keyboard
seems to be the chief aim and object of every young pianist.

Years ago there were not so many inventions for making learning
delightful to the young, and we distinctly remember the fierce battles
which used to take place at each music lesson over this very wrist
business.

As no wrist-guide had then been invented, necessity--which is the mother
of invention, they say--taught our instructress to make one of her own.
Hers was more simple than the present one, but probably even more
