This is a version of my printable blank fingering chart for contrabassoon. Contrabassoon key work is far from standardized, so it was hard to pick exactly what to include. I ended up emulating the Fox contrabassoon owned by my school, which I think is fairly middle-of-the-road in terms of key work. The actual fingering diagram here is based on one from Bret Pimentel’s Fingering Diagram Builder.
