Four Transformations collects excerpts from four granular alterations of a single sound source. A solo double bass performance was run through four different configurations of the Granulab synthesizer program, with each configuration selected to exploit a given aspect of the original performance, such as its phrase structure, overtones, pitch relationships, etc.

Solo double bass recorded on 3 v 2013 in Silver Spring MD USA. Granulation performed 10 v 2013.
