It was all too easy for me to adjust the tuning of any particular note on my oboe, unfortunately usually in the wrong direction. The violin players in front of me, who had much better pitch recognition than me, would shoot me dirty looks and I'd get my pencil out to mark up the sheet music with arrows pointing up or down.

Ah yes, forgot about oboe (and bassoon and English horn and double-reeds in general), which tend to be much more sensitive about embouchure when it comes to pitch if I remember right.
