About klang²
20 sound squares turn your ears upside down. Which bird sings? Which composer sounds? Can you put proverbs together and recognize foreign languages? Place your smartphone with the klang² app open in the middle of the table, place a sound square on the reader and listen carefully: Off you go with your acoustic game collection! ATTENTION: This app only works together with 20 sound squares, which are available via klang2.com.
