Self-Help for Singers by David C. Taylor
New Light on the Old Italian Method by David C. Taylor
Position and Action in Singing by Edmund Meyer
The Head Voice and Other Problems by D. A. Clippinger
The first and last of these five identify problems with voice training that were rampant 100 years ago which are still very much with us. I shake my my head at how far we have not come with all of our science and mechanics about the voice. The idea that a voice could be trained to a very high level of artistry and technical freedom before the age of “voice science” is unacceptable to most people, but why?
As you can see, I have been reading a lot of David Clark Taylor recently. His work influences mine greatly. His rationale for what the “Old Italian Masters” taught, and why it has been abandoned, is very compelling. If that whole topic interests you, I can think of no better author from any era to start with.
There is also a plethora of links to downloadable books on Daniel Shigo’s website. Kudos to him for making them so easily available.
