First-rate flute player Harry Bradley is now offering flute lessons over the Internet, by exchanging MP3s. Interesting idea, as it opens the door to those who can't make it to Ireland to get lessons from Harry in person.
It might at first seem like such lessons would be necessarily limited — the teacher won't be able to see your grip, embouchure, etc. But we're producing music, not visual art, here, and the audio carries a heck of a lot of information, especially for a skilled listener. Studying with June McCormack's excellent tutor Fliúit has really sold me on the virtues of having well-played slow audio of the tunes I study. Without seeing her play or talking to her, I feel like I'm getting formal instruction just by listening and playing along to her tracks. I'm sure that having tutorial recordings made just for you and having your audio heard by a teacher would be even more beneficial.
With all that said, I don't think I'll be signing up just yet, for the same reason I haven't booked tickets for the Frankie Kennedy Winter School: I'm still new to this instrument and I feel like I have a lot more of the basics to learn from my teacher here in town before I start working with folks from overseas. But I really, really look forward to the day when I'll be good enough to make such efforts worthwhile.
Speaking of the Frankie Kennedy Winter School, Bradley teaches there, too, and you can get several MP3s for study (albeit not slow ones) from him, Téada, Robbie Hannan & Dermot McLaughlin from the Winter School site.
