It's strange that a flute should (as a whole) go seriously flat since it's constructed in a fixed way. Pianos go flat because the strings start to stretch, other strung instruments can be tuned easily, but a flute?
I also know that w/w instruments can be tuned slightly for orchestral playing except the oboe which is why it sounds the A in orchestras.
Does it still play in tune even in flat? I wondered if there's some component in the head joint that's 'set' by the makers to get it in tune and it's come out of adjustment? I don't know much about flutes tho. Just seems strange that it
could go very flat.
A couple more semitones and you can turn it into an alto?

All woodwind instruments can be tuned down to an extent. With the flute it's a case of pulling the headjoint out so the overall length of the tube increases. Flutes are designed to be in tune when the headjoint is pulled out several millimetres, not when pushed completely in. The stopper in the top of the headjoint is a vital part of keeping the flute in tune, and if this is not adjusted correctly there can indeed be major tuning problems.
