  High-quality data from space-based observatories present an opportunity to
fit stellar models to observations of individually-identified oscillation
frequencies, not just the large and small frequency separations. But such fits
require the evaluation of a large number of accurate stellar models, which
remains expensive. Here, we show that global-mode oscillation frequencies
interpolated in a grid of stellar models are precise and accurate, at least in
the neighbourhood of a solar model.
