This book by Ryan Malone is intriguing. I highly recommend this book to all musicians and singers, especially worship leaders.
First off, it is free. Yes, free. I found it online and was able to order a hard copy from the ministry. It took a few weeks to show up in my mailbox, but when it did I was excited.
A very clear, complete and concise picture was painted for me as I read about the music of heaven compared to the music of earth.
Introduction: Expanding the Throne Room Culture
This book offers a fresh perspective on worship music.
I enjoyed reading about how music in heaven existed before earth. I liked reading about ancient cultures using harmonies and sophisticated and complex forms.
Overall. Great book.
