The first in my series of articles looking at singing is the post below. You can read it here, in the blog, or download a PDF from the "Singing Words articles in PDF" page in the Singing Words menu.
The digested read for this is pretty brief. A lot of research has looked at how best we can improve our motor skills, physical skills of coordination, in any particular activity. For singers, this is relevant to an approach to teaching I have called "techno-physical". Techno-physical approaches tackle head-on the physical and anatomic side of singing. For a full discussion, see the second post of all in this series.
A large part of the research into motor skills has asked what kind of focus it is best for learners to adopt: an internal one, on their own body, or an external one, on the intended effects of their actions.
By and large, though not quite completely unanimously, most research points to external focus points being more effective in learning.
This might be interesting for singing teachers given that some ways of teaching technique, particularly techno-physical methods, require an internal focus.
The article, "Effects of the Focus of Attention on Learning", presents a broad view of the research and considers what use singing teachers can make of it.
