I use this keyboard improvisation worship book in teaching classical piano majors at Biola University, most of whom do not have much improv experience. These students can read however. So, this book is particularly useful for those who read music. The book starts simply but gets more complex as it develops. Use the 27 chapters in whatever order you like. Jump around and see what suits you. I focus mostly on many kinds of harmonic possibilities – less on rhythmic intricacies, though you will find some blues and salsa too. Hundreds of worship chorus and hymn fragments demonstrate various techniques. Also, hundreds of exercises are available for you to complete and test your skills, whatever your level of accomplishment.
