Abstract: Stars and star clusters are the fundamental visible building blocks of galaxies in the present day, as well as in the early universe. Today, star formation is controlled by the complex interplay between self-gravity and supersonic turbulence in the interstellar medium. Turbulence plays a dual role. On global scales it provides support, while at the same time it can promote local collapse. This determines the statistical characteristics of a stellar population such as the initial mass function or the spatial distribution of stars. The role of turbulence in primordial star formation is less well understood. In this contribution, we discuss results from recent numerical calculations that study the influence of turbulence on stellar birth in zero-metallicity and low-metallicity gas. Special emphasis lies on the distribution of stellar masses and their dependency on metallicity.
