First published over seventy years ago, this imaginative series of studies is as useful and relevant now as it ever has been.Each volume has studies composed by well known and lesser known composers and is carefully graded to offer a variety of keys, time signatures, textures and tempi, whilst each study is given a title which tells the student exactly what it is trying to achieve.These books provide invaluable practice material for the building of technique and are also enjoyable to play in their own right.
