So I've been playing through a lot of pieces and have noticed that the b above the octave g is sometimes written as a harmonic, for example in bottesinis concerto no. 2 second movement(that's where I noticed it most recently). As far as I'm concerned I can't play that note with a harmonic because they sound an octave to high. Is this because I'm in orchestral tuning instead of something else? Or am I maybe missing a harmonic on the fingerboard or supposed to make an artificial harmonic... If anyone could clear this up for me it would be helpful. I could also send post pictures of music with it if it's helpful.
