Someone talked about tenor if you sing tenor. I sing alto so want to go below middle C. So what I'm aiming to do with my new recorder is play / read an octave higher (as descant is) when I'm learning Dixit Dominus (I know there are other ways to learn it but thought it might help get the finger/co-ordination). And I suppose I'll have to play in true pitch if playing treble arrangements.
Piva have an Early Music course at Halsway that they say is not just aimed at expert players. So maybe.. If I practise.
Yes, I do find that going from one page to the next I'm suddenly in descant fingering!
I took Jacks advice for the Yamaha descant (my old green descant has a tiny crack, but I'd been happy with it), so thought I'd get a Yamaha treble too. So far so good, not too hard to get the second octave (except F, which I have trouble with when singing, too). And I like the sound. I do have an old (21st birthday present) Schott wooden treble but I never play it because it's not in tune (I melted on the windowsill), and I never learnt the fingering reliable after realising that the alto line needs transposing an octave.
