My son has written a 288 page practice book for scales in every key. If any of you have ever published a practice book (or any book for that matter), how did you get it done. He was the top Music Comp student at East Caroling in 2015. He was among the top getting his masters in comp at Louisville. Some of his past instructors have said it was great, and they would encourage their student to buy/use it when it came out. He's tried to find someone who would publish this. Any ideas?
