Summary: In this paper we introduce the concept of a progressive percussion graph as a musical space and the metaphor of composition as the musical expression of a traveling experience in that space. A Progressive Percussion Graph is a directed graph where each node is associated with a particular percussion rhythm and each connection corresponds to a rhythmic progression, generated through optimization processes, from one percussion rhythm to another, respecting the connections direction. We have explored different optimization techniques and different path-finding algorithms resulting in a rich and diverse musical output.
