With martle on that one - bassoon and horn have been blending OK for centuries in Harmoniemusik and elsewhere but the flute is a tricky business. On the other hand take it away and you really wouldn't have a top on the ensemble to speak of.
Do you think that's because of the thick syrupy sound that is encouraged from the modern metal flute? Bazooka-size bores seem to encourage a playing-style that's strayed many miles from the sound of "traditional" flutes. Translucent sweetness seems to have gone out of fashion
It's true that
Dauervibrato is something that's only encouraged on the flute among the instruments in the wind quintet. Without that you'd stand more of a chance. There are a few period-instrument wind quintets -
Das Reicha'sche Quintett for example, who have recorded not only Reicha but Danzi. (On the other hand they haven't done Hindemith or Ligeti or Birtwistle (anyone else a fan of
Five Distances?) or Holliger for some reason.)
But speaking of period instruments, anyone else know this quintet?
