Yodelers taking part in an annual Swiss festival in Basel use city fountains as improvised rehearsal spaces after extreme heat in June. Multiple outlets report that during the heat wave, participants sing and practice yodeling in and around the fountains, effectively turning them into cooling and staging areas. The event is described as the Eidgenössisches Jodlerfest, a Swiss gathering featuring traditional alpine music and performance. Sources also note that the festival includes competitions and performances such as yodelling, alphorn playing, and other activities including flag-throwing. While the reports differ only in emphasis, they agree that weather conditions are the driver for the unusual setup: organizers and participants adapt to high temperatures by making use of nearby water features in public spaces. The accounts present the fountain rehearsals as a practical response to the heat rather than a separate attraction, reflecting how public events adjust when conditions become uncomfortable or unsafe.
