Interesting to read the more technical detail about singing voices: I must ensure that the female family fractions (or do I mean factions?) read it when they return from this weekend's singing.

As a mere ignorant male non-singer, is it purely a matter of singing high or low? I suspect it was one of my posts that Richard read, where I queried the apparent shortage of new powerful female voices. I don't think that (for example) Maddy Prior or Maggie Boyle can be accused of having other than powerful voices, however high they sing. But the younger breed that I've heard seem weaker. No names, ok.

Is there a more technical term for this? (Just what does timbre mean?)
