By drawing concept diagrams of Smalley's seminal writings, I have attempted to show how Smalley's ideas on acousmatic music have evolved from manipulating sound objects to creating ‘space-forms’. The work Wind Chimes is analysed with respect to spectromorphology and sound shapes, and it is compared to the work Base Metals, which is analysed with respect to spectral space. A connection is then made between the evolution in writing and the evolution in composition.
