BTW, I'm loving my new Hammig piccolo! Such sweet sounds!
Well, most are sweet sounds. My high B-flat is worse than fingernails on a chalkboard if and when it comes out. Sometimes I can't get the note at all. It's not the horn, it's me on any piccolo. Any tips?
If you continue to have problems with most of these fingerings check that the Bb key is being closed properly by the F key (and try the lever by the F key or the thumb plate). If you can locate an old publication eg Otto Langley you will find some different basic fingerings!
