Our little recorder group of seniors has been taught to cover up the 2nd from the bottom hole (soprano recorder) whenever we play G to D above Middle C. The director has us doing that to try to get folks to not sound so sharp, I believe. In the meantime, I’ve been forging ahead and working on more difficult music and now I’m beginning to wonder if that might actually be a bad habit to get into when I am working with runs and arpeggios. It seems to slow me down having to do the regular fingering and then remembering to hold that other finger down.
If it is a good and standard practice, I’ll keep on and just work my way through it but if I should “cease and desist”, I’m game to do that, too. I don’t seem to have a problem with sounding sharp or flat. I think it’s my french horn background where I just learned to adjust the pitch with my embouchure.
