In only a decade, seismology of red-giant stars has grown from infancy

to adulthood in the study of stellar structure and evolution. The

stimulants for this accelerated growth have been space observations,

first provided by the WIRE star-tracker and MOST, and continuing with

CoRoT and Kepler, having detected oscillations in thousands of cool

giants. However, almost all of the stars in this impressive sample are

faint, with little known about their basic properties. Even reliable

spectral classifications are lacking for many of them. MOST is the only

space-based photometer capable of continuous observations of bright red

giants for which we have independent constraints (e.g., spectroscopy)

essential to extract the internal structure from the stars' p-modes.
