International Crumhorn Day is celebrated on October 3rd, focusing on the unique double reed woodwind instrument known as the crumhorn. This day was founded by a group of musicians called Whistlebow to promote appreciation for this distinctive part of Renaissance music. Observers are encouraged to engage with the crumhorn by listening to performances, whether through online platforms like YouTube or Spotify, or by trying the instrument themselves if they have access. The crumhorn, which features a characteristic bent shape resembling the letter "J," has seven finger holes and a thumb hole, with its name derived from German, meaning "bent horn." The day serves as an opportunity for both enthusiasts and newcomers to explore the instrument's history and sound.
