How this board opens

This one opens itself. One sweep of the overlap rule — every row read against its clue lengths, then every column — is worth 193 of the 225 cells, 86% of the board, before you have deduced anything of your own. The most generous opening is row 1, which gives up 15 cells on its own. 6 of the 30 lines are decided outright by their clues, with no room to slide. From there the board finishes on row-and-column logic alone — there is no point where you have to try a cell both ways and see which one breaks. The finished picture fills 78 cells, and the longest unbroken run anywhere in the clues is 12.

About this category

Two related shelves sharing one room. On one side are instruments — a harp, an accordion, a marimba, a leather drum, panpipes, a flute, a tambourine, a piano keyboard, a sheet of notation and a single quaver. On the other is the gear that captures and plays things back: a clapperboard, a film reel, a television, a webcam, a security camera, a loudspeaker, a set of VU meters. The two halves look unrelated until you solve a few and notice they fail in the same way.
