Most of the stars pulsate like tuning forks, singing a song precisely correlated with their internal structure. Helioseismology has shown since about forty years that the Sun could be probed down to its very internal layers. The solar helium abundance, the depth of the convective envelope, the internal law of rotation, the distribution of the sound speed throughout the Sun, all these results are tremendous successes obtained from the analysis of solar pulsations. Similarly, asteroseismology is a blossoming field and ground-based observations and especially space-borne missions, coupled with more and more precise and complete theoretical models, are due to allow us to enter the stars and "see" what physical processes are at work.
