brett manning is a student/disciple of seth riggs. he is teaching a variation of speech level singing. the reason this program works is it encourages use of your natural voice in singing. we speak in varied and wide ranging pitches. singing is sustained speaking. so if you can talk you can sing. most voice lessons ive been to (workshops etc) make singing some mysterious art that takes tears of training and practice. brett mannings program is pricey but it is less expensive than months of lessons.
i have it i employ the techniques with my church choir (shhh)
