Portrait of Karangahape Road is a jazz composition built from harmonic structures generated through spectral analysis of a field recording of Auckland's iconic Karangahape Road. The field recording was processed and filtered several times using spectral analysis software. Through this process, pitch information emerged from prominent frequencies in the original recording, which I arranged to form this composition for piano and soprano saxophone. The composed material establishes the atmosphere and thematic material, which is expanded upon through free improvisation to create a complete and evocative work. This was recorded live in my home studio, with saxophone provided by Chris Mason-Battley.
