Composed for and dedicated to Stanislaw Skoczyński, Spider Walk is a multiple percussion work based on the additive number sequence . This creates the additive sequence of 1, 2, 3, 4, 5, 6. Throughout the work, Ptaszyńska uses this additive sequence in many different ways. She beings by using it to create a fast-driving, rhythmic section. Then she transitions to a slower, more passionate section that delves in the exploration of space. After, there is a return to the fast-driving motive but containing multiple variations. This is concluded with a slow, quiet coda that pulls material from the prior music. Spider Walk was premiered in 1993 at the Percussive Arts Society 1993 Convention.
