==== Topography ====
Analyst Kathryn Bailey has used the term 'topography' to describe the particular way in which the notes of a row are disposed in her work on the dodecaphonic music of Webern. She identifies two types of topography in Webern's music: block topography and linear topography.

The former, which she views as the 'simplest', is defined as follows: 'rows are set one after the other, with all notes sounding in the order prescribed by this succession of rows, regardless of texture'. The latter is more complex: the musical texture 'is the product of several rows progressing simultaneously in as many voices' (note that these 'voices' are not necessarily restricted to individual instruments and therefore cut across the musical texture, operating as more of a background structure).<ref>{{Cite book |last=Bailey |first=Kathryn |title=The twelve-note music of Anton Webern: old forms in a new language |date=2006 |publisher=Cambridge University Press |isbn=978-0-521-39088-0 |edition=Digitally printed 1st pbk. version |series=Music in the twentieth century |location=Cambridge [England] New York |pages=31}}</ref>
