While I may not be the best person to offer a review, I promised, so here goes.
We’ve previously discussed an instrument called a “flutina” ( www.flutina.com ). This instrument should not be confused with the 1940s plastic recorder by the same name. While is looks superficially like a six-hole fife, it is actually a six-hole fipple flute (whistle) with an internal airway. You blow into, rather than across, a smallish round hole offset about 45 degrees “below” the fingerholes. The airstream is conducted through a passage and exits across a whistle-type blade on the side opposite the airhole.
Superficially, the ‘flutina’, hereafter referred to as the ‘whistle’, is wood, painted various colors. The one I have is a sort of stippled silver/black. They photograph better than they look in the flesh, where the the paint job seems somehow cheap. Dimensions: L 14", dia. 13/16", wall thickness just under 1/8". As would be expected. it feels heavy. The fingerholes are all about the same size, cleanly drilled but the paint doesn’t help the finger seal.
OK, the important stuff: Key is C. The bell note is slightly flat. The whistle is almost but not quite in tune with itself. All notes show flat on a tuner, but the amount varies slightly. The tone is woody, somewhat recorderish. The whistle blows hard. I suspect it to be caused by the length of the airway and possibly the convoluted airflow path. It is realistically only good for about an octave and a half, you can go higher, but anything above the second F is too much work.
Its playable, and pleasant sounding within it’s limitations. Personally, I have little use for a C whistle, but if I do , it likely won’t be this one.
Conclusion: Save your money.
