First effort is a D major flute, 6 hole. Came out good but not great, it plays a little flat.
Fortunately, each 24" tube costs less than a buck. So anticipating my first would not be great I got three tubes. The first one showed me where the holes should be relative to my own fingers. So I'll do it again, rotating those holes to where I want them, but getting the initial length right.
Once that's complete I'll try a Fajardo wedge in the third iteration.
Then there's the matter of a proper embouchure on my part lol
