Throughout the last century, Jazz music experienced different stages; in the 1920's most people were dancing to the music, whereas now it mostly serves the purpose of listening. With Echonest, it was possible to analyse a piece of music and calculate its danceability and energy.
"Data Dance" visualizes three chosen pieces of jazz from different times, and displays them on a grid, using the human body as the primary tool of communication. Danceability on the x-axis, energy on the y-axis, and the tempo is represented by the colour of the gradient, surrounding the dancer. Slower tempo is indicated by darker purple colours, whereas lighter tones represent an increase of the tempo.
Whenever the music is experiencing low energy, one tends to dance more with the feet. High energy affect the upper body.
Danceability varies from minimal movements, such as a step forward, to more erratic movements, like kicking your leg in the air.
