Firstly, Spaw: my inexpensive digital camera does not allow audio recording; and, secondly, as I said in the About me section, folks can, if they wish, give this video a viewing while they listen to my tracks, above it.
And, yes, I do move the recorder/English flute around in my mouth quite a bit - as I at least try for a good timbre, and to match recorder and voice (play like I sing/sing like I play).
