The September 25, 2026 puzzle ran from a trumpet at 48 cm to a double bass at 1.8 m — about 4× apart, drawing on music. The pair furthest apart was round 5: a concert flute is 1.5× as big as a domestic cat.
Puzzle #4 asked about a concert tuba, a trumpet, a double bass, a trombone and a concert flute. Each answer below gives the measured size, the reference it stood beside and the source behind the number. Want the surprise first? Replay this puzzle — archived days never touch your streak.
Answer: Concert Tuba — 1 m. 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: Trumpet — 48 cm. A trumpet measures 48 cm (length / span), which is about 1.4× smaller than the reference, a French baguette at 65 cm.
About 1.5 m of tubing, wrapped into 48 cm of instrument.
Common miss: players tend to inflate a trumpet when it sits beside a French baguette — big things get squeezed, small familiar things get stretched.
Answer: Double Bass — 1.8 m. A double bass measures 1.8 m (height), which is almost exactly the same size as the reference, a refrigerator at 1.8 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 refrigerator — big things get squeezed, small familiar things get stretched.
Answer: Trombone — 90 cm. A trombone measures 90 cm (length / span), which is almost exactly the same size as the reference, a baseball bat at 86 cm.
Measured closed — running the slide out to seventh position adds more than half a metre.
Common miss: players tend to compress a trombone when it sits beside a baseball bat — big things get squeezed, small familiar things get stretched.
Answer: Concert Flute — 67 cm. A concert flute measures 67 cm (length / span), which is 1.5× as big as the reference, a domestic cat at 46 cm.
Played sideways, which makes its 67 cm read much smaller on stage.
Common miss: players tend to compress a concert flute when it sits beside a domestic cat — big things get squeezed, small familiar things get stretched.
