A hootenanny is a fancy word for a big party where people get together to sing songs and have lots of fun! Just like when you have a birthday party with your friends, but instead of playing games, you are singing your favorite songs with everyone else.
Usually, at a hootenanny, people will bring their own instruments like guitars, ukuleles, or banjos, and they will take turns playing and singing. Sometimes people even bring drums or harmonicas to play! Everyone is happy to share their music with each other, and you can learn new songs as you listen.
At a hootenanny, people also like to dance and move around while they sing. You don't have to be a perfect singer or dancer. Everyone is there to have fun and enjoy each other's company!
It's like a big musical party, where everyone is welcome to sing, dance, and have fun together!
