Music school students can develop their technical skills by means of a ''game'' lasting throughout a year: this volume contains 52 pieces, thus providing an etude for every week of the year. These short works are not dry finger exercises, but well-rounded little compositions. A conscientious student who works through them all in the course of a year will find they offer help in solving every kind of technical problem. At the end of the volume a few more etudes, longer ones suitable for performance, are included as supplements.
