Internal properties of stars with convective envelopes are determined by analyzing the frequencies of their acoustic modes. After a brief introduction to observational techniques, I will describe the emission, absorption, and scattering of sound inside a star and how the waves ultimately escape through its photosphere. Then I will demonstrate how these processes account for some remarkable regularities revealed by observations of solar modes across 3 orders of magnitude in angular degree.
