This book will prove useful as supplementary material for all those who are perhaps a little vulnerable rhythmically. Starting with dotted crochets and progressing through to 5/8, 7/8 and changing metre, the pieces repeat rhythms in different settings, enabling players to make otherwise difficult connections. Some of the keys are challenging, for example the second piece "Japanese Dance" is in 3 flats making it really quite tricky and there are is one piece in A major. The CD is good though, and overall this book is worth the money.
