ROUND 1
Concert Tuba — 1 m
Answer: a concert tuba measures 1 m (height), which is almost exactly the same size as the reference, an acoustic guitar at 1 m.
Up to 5.5 m of tubing, wrapped into about a metre of instrument.
Common miss: players tend to inflate a concert tuba when it sits beside an acoustic guitar — big things get squeezed, small familiar things get stretched.
Answer: a double bass measures 1.8 m (height), which is about 1.1× smaller than the reference, a US interior door at 2 m.
Tall enough that players either stand or perch on a stool.
Common miss: players tend to inflate a double bass when it sits beside a US interior door — big things get squeezed, small familiar things get stretched.
