I responded: "YES, the book is definitely designed to be sung from--it is oblong, music printed in shapes, solid paper, in two volumes so that each vol. won't be heavy to heft, and with six indices so that people can find a piece by composer name, text author name, poetic meter, first line of text, text subject, and (unique in my experience) musical features--and we're going to keep the price down all we can.
Yes, it'll be more expensive than other books--I don't know the likely price yet--but I believe purchasers will cherish what they've got, when they hold it in their hands and page through it and see not only the wonderful music but the beautifully reproduced illustrations, the many performance suggestions that I include in the commentary, and the hundreds of detailed composer and arranger biographies.
I haven't counted pages, but I'd say that the book will be 2/3 music and illustrations, 1/3 all else.
I honestly believe that anyone who loves this music and the culture/s it came (and comes) out of won't be able to be without American Harmony.... American Harmony will be three things: a book to sing from, a scholarly monument, and an object of beauty."
