In order to help the detection and identification of low-frequency p- and g-modes in the solar spectrum observed by ground-based networks and SoHO experiments, we study the properties of low degree ('=0 - 6) low-frequency (100 - 2000 Hz) solar oscillations. The frequencies of p- and g-modes have been computed for a set of solar models with updated physics. We point out the specific properties of the oscillations of mixed character, with noticeable amplitude both in central and external layers. We analyze the sensitivity of low-frequency oscillations to solar parameters like age, metallicity and lumi- nosity, and to various physical processes, like convective core overshoot and mass loss during the beginning of solar evolu- tion. We estimate the sensitivity of the splittings of these low- frequency oscillations to the core rotation.
