Well I was just wondering if anyone knew about a very super low D. Or I think it would be a D. Lower than that oh so low Eb. I don`t think it is possible on my instrument, but I have it in one of my songs for the Catata Orchestra thing I am doing. I am confused. So can anyone tell me the fingering-if there is one. I`ve been playing Bb bass clarinet for about 5 years now and don`t recall ever coming across this note. Help?
