  In the paper we discuss the sonification of the simulated gravitational wave
data for the future LISA space mission. First, we introduce the LISA project
and its output. Then, we present Einstein's Sonata, a multimedia project
devoted to the artistic public display of the LISA data. Einstein's Sonata
features as its main element a music composition for prepared piano, Periplo
del latte. The latter results from a sonification strategy mapping astronomical
data onto music. We thus detail a four-stage sonification procedure, that
features two data preprocessing stages, a mapping into an abstract control
space and finally automatic notation generation.
