The purpose of this book is to be presented as a guide in order to provide the proper piece of knowledge to the improviser, either for a beginner or a sophisticated and well educated professor. A textbook that will surely accompany him from his first musical steps and also become an instructor for this endless journey of improvisation. This book includes Greek and international terminology for the reader in order to get familiarized with the universal language of music. I wish everyone have a wonderful journey into the world of improvisation and music in general…
