I've always been a fan of Ian Anderson, and would appreciate it if someone could elaborate on how he sings into the flute and other such techniques. And so today I found out that… Singing into the flute is a common extended technique that flutists use with modern music. To do it, try singing a note (without your flute) and just hold it out. Now, still singing that note, bring the flute to your mouth, form your embouchure, and blow your flute as usual. Your air will be producing the singing tone and the tone from the flute at the same time. It takes some coordination but it's actually not too hard to learn. It's also a good technique to make sure your throat is open and relaxed while playing.
