Zig zag zig,
dance macarbre, cazalis.

Zig ,zag,zig,deathin a cadence,
Striking with his heel a tomb,
Death at midnight plans a dance-tune,
Zig,zag,zig,onhis violin,
The winter wind blows and the night is dark;
Moans are heardin the linden trees.

through the gloom, white skeletons pass,
Running and leaping in their shrouds,
Zig,zag, zig, each one is frisking,
the bones of the dancers are heard to crack,
but hist! of a sudden they quit the round,
They push forward, they fly, the cock has crowed.
