  While Kepler has pushed the science of asteroseismology to limits
unimaginable a decade ago, the need for asteroseismic studies of individual
objects remains. This is primarily due to the limitations of single-colour
intensity variations, which are much less sensitive to certain asteroseismic
signals. The best way to obtain the necessary data is via very high resolution
ground-based spectrography. Such observations measure the perceived
radial-velocity shifts that arise due to stellar oscillations, which exhibit a
much better signal-to-noise ratio than those for intensity observations. SONG,
a proposed network of 1m telescopes with spectrographs that can reach
R=110,000, was designed with this need in mind. With one node under
commissioning in Tenerife and another under construction in China, an analysis
of the scientific benefits of constructing additional nodes for the network is
warranted. By convolving models of asteroseismic observables (mean densities,
small separations) with the anticipated window functions for different node
configurations, we explore the impact of the number of nodes in the SONG
network on the anticipated results, across the areas of the HR diagram where
solar-like oscillations are found. We find that although time series from two
SONG nodes, or in some cases even one node, will allow us to detect
oscillations, the full SONG network, providing full temporal coverage, is
needed for obtaining the science goals of SONG, including analysis of modes of
spherical harmonic degree l=3.
