Probably Poland's most iconic sound, the hejnał mariacki (literally "Saint Mary's dawn") is a trumpet call that sounds every hour on the hour from the highest tower of St Mary's Church in Kraków's rynek glówny (main square). 

The bugler plays the same call four times, once in each of the cardinal directions. This tradition dates back to medieval times, when the call was used to signal the opening and closing of the city gates at dawn and dusk. It was also played to alarm citizens of fires or enemy invasion. 

The theme's abrupt end commemorates the Mongol-Tatar siege of 1241, when the trumpeter warning the city of the imminent threat was shot in the throat by an arrow mid-way through the call. 

Or so the legend goes... I made this recording a couple of months after moving to Kraków as part of a project through which I attempted to reconnect with my Polish-Jewish heritage and, in a more general sense, to explore the experience of migration through sound.
