An excellent first guide on organ registration. I had many doubts about combining stops and some of their functions, and I found the answers in this book. I'll have it constantly with me when practising, so as to master this subject.
I had a difficult time trying to relate this to my playing on an electric organ. My lessons are on a pipe organ, which I much prefer, but I have minimal access to it. I think that the basic concepts are a bit clearer after reading it, but I need to reread it and discuss it with my instructor.
For a concise, understandable explanation of organ registration, this book is the best. Organ registration is a vital skill for every organist, but to the beginner the task can seem quite daunting. James Engel will take you through the reasoning, the historical background, the and individuality of different instruments to make the theory plainer, and he offers practical practice suggestions too!
