Free Museum Speelklok roadshow: children make Utrecht music machines sing

From 18 July to 26 August, the free Museum Speelklok Roadshow stops at eleven Utrecht neighbourhood locations. It suits families who want a one- or two-hour hands-on introduction to mechanical music. Check the exact venue and time for your date; in bad weather the activity moves inside the museum, where children can still work toward an organ diploma. Each stop places mechanical music in a playground, farm or garden children already know, turning old technology from something behind glass into sound started by one hand.

• This is a travelling music-machine museum: stops range from Fort aan de Klop and playgrounds to a city farm, garden and windmill, bringing hand organs, music boxes and playing clocks into places children already use.
• A child's hand is the start button: visitors turn an organ, explore the mechanism, follow the Toon treasure hunt and make music. The organ diploma turns casual play into a small mission with an ending.
• Why that matters: changing the turning speed and hearing the result reveals that music can come from gears, air and human motion. Every stop has its own hours, so the overall date range is not enough for planning.

Hokimi field note: Ask what will happen if the handle turns twice as fast, then let the child test the prediction; one question turns a noisy attraction into a mechanical experiment.
