As the Kepler time series grew, so did the interest in the asteroseismology of very low-frequency solar-like oscillators. It is possible to accurately resolve modes for stars near the tip of the red giant branch. Our analysis of M-giant stars shows that both radial and non-radial modes are well defined in the spectra and form a triplet mode structure. By comparing the data to theoretical models we have successfully classified the angular degree and radial order of modes in 195 evolved red giants.
