The latest instructional DVD release from The Murphy Method is Harmony Singing Made Easy, featuring Bill Evans, Janet Beazley, and Chris Stuart along with Murphy Henry.
Using some very familiar jam session standards – Will the Circle Be Unbroken, Bury Me Beneath the Willow, All the Good Times Are Past and Gone, Don’t This Road Look Rough and Rocky, Amazing Grace, Over in the Gloryland – Murphy and company demonstrate three and four part harmonies in a variety of keys.
In fact several of the songs are presented in three different keys, alternating between male and female leads, to make sure that a suitable key for the viewer to try singing the various vocal parts is available.
For each song, the complete vocal trio (or quartet) is performed, followed by a demonstration of the different parts in turn.
Here’s a brief trailer:
