The October 9, 2026 puzzle ran from a violin at 59 cm to a double bass at 1.8 m — about 3× apart, drawing on music. The pair furthest apart was round 3: a violin is about 1.3× smaller than an alto saxophone.
Answer: Drum Kit — 1.5 m. A drum kit measures 1.5 m (length / span), which is 1.2× as big as the reference, a 55-inch television at 1.2 m.
Kit width is set by the bass drum and how far the drummer’s arms can reach.
Common miss: players tend to compress a drum kit when it sits beside a 55-inch television — big things get squeezed, small familiar things get stretched.
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.
