Agrell makes a convincing argument...that learning to improvise should be part of the training of any serious musician. Improv Games for One Player provides a wealth of source material for aspiring improvisers. I can't think of a musician who wouldn't benefit from this book.

This book is intended for all musicians...would be quite useful for classical musicians with a good grounding in music theory that want to get experience improvising in a way that builds upon traditional classical music education...would also be valuable for instructors of all levels because it provides good exercises for improvisiation that can be as simple or as complicated as needed.

Improv Games for One Player is a fantastic resource for teachers and players alike. Derivatives of some of the exercises can certainly be used with beginning and intermediate students. Doing so may even provide the extra inspiration needed to learn those scales and arpeggios. As Agrell advocates, improvisation serves as an important component in achieving "comprehensive musicianship." Including this book on the music stand will provide a varied and thorough approach by which to begin the path toward this lofty goal.

Improv Games for One Player is an addictive book of musical games designed to help you be more expressive and musical in your music-making. This slender book should fit in just about every case with enough room to transport a sheet of music paper, but still contains plenty of games to enliven and enrich a player’s daily technical and musical practice. About half of this material is drawn from the original Improvisational Games for Classical Musicians, and half from new, previously unpublished material collected and invented by the author.

Who should improvise? All instrumentalists and vocalists. Everybody. No experience in improvisation necessary!

When should you improvise? Now. Every day. As much as possible.
