The manifesto, the text, on one or several A4-pages, is cut into one long strip to fit a music box and then spliced with tape. Some manifestos has been scanned from top to bottom (vertically) and others from left to right (horizontally). The letters D and A in the text are then punctuated, so the absence of D and A (..DADA), is what you hear being played.
The first dada manifesto by Hugo Ball (1916) encourages poets to stop writing with words, but rather write the word itself, and Ball states that:
"I shall be reading poems that are meant to dispense with conventional language, no less, and to have done with it"
In this way this collection of Dada Manifestos acts in accordance with Ball's manifesto, using the word construct as the direct source.
