“The Blackbird,” like “King of the Fairies,” is one of the five traditional set dances, which means that there are specific steps that have been choreographed to dance to it. You can see it danced here. Like “King of the Fairies, “The Blackbird” has a regular-length A part and a longer B part, and both parts are repeated. But if the tune feels a little odd or crooked, that’s because it is. The last measure of each A part is a 2/4 measure, and the B part is similar, with a 2/4 bar at the end of each eight-bar section. Marla walks you through the A part in this video.
