Early experiments have suggested that program auralization can
convey information about program structure [5]. Languages like
Pascal contain classes of construct that are similar in nature
allowing hierarchical classification of their features. This
taxonomy can be reflected in the design of musical signatures
which are used within the CAITLIN program auralization
system. Experiments using these hierarchical leitmotifs should
(see note in EXPERIMENT section) indicate that their
similarities can be put to good use in communicating
information about program structure and state
