About
The ‘Rolf Sounds’ app belongs to the ‘AR puzzel De band’. On the puzzle, there's a band, consisting of 10 children, each with a musical instrument (bell wreath, triangle, maracas, cymbals, trumpet, guitar, violin, djembe, keyboard and saxophone). Use the app to scan the instruments. You hear the sound and see a photo of that instrument on your mobile device. By scanning the painting, you hear and see several instruments.
Plan
1. Complete the puzzle and see the band and the instruments.
2. Launch the 'Rolf Sounds' app.
3. Point the camera at an instrument on the puzzle or the painting.
4. The app recognises the instrument or the painting.
5. View the photo and listen to the sound of that/those instrument(s).
The puzzle and other AR puzzles are available to buy at www.derolfgroep.nl
