I normally play recorders in sessions. When somebody starts playing a Dixon or Susato high D, I switch to something that plays in a different octave.

All cylindrical bore whistles go flat in the high register, and Dixons and Susatos go VERY flat and VERY loud. A recorder doesn't, even a cheap one - I can stay dead in tune with accordions and fiddles. But the shrieking dissonance of two high fluty things playing a high A a quartertone apart is not something I want to be part of. Listeners can't tell which one is the culprit so if I just back off they'll know it isn't me.

Please get a Clarke or save up for a Burke instead.
