Spectral Density Estimation is a pair of sculptures commissioned by the SECCA and the Winston-Salem Symphony orchestra. Two sound recordings of the first organized tuning were taken at the last 2 orchestra performances of the 2012 / 2013 season. Each recording was analyzed and transformed into a spatial arrangement of the audio frequencies over time. The resulting geometry was then carved into a block of wood from a cedar tree, that had fallen outside the museum.
