## Abstract

Recent progress in the studies of pulsating variable stars is summarized from an observational point of view. A number of unexpected phenomena have been revealed in the case of pulsators in the classical instability strip. These discoveries -- lacking theoretical explanation yet -- make pulsating stars more valuable objects for astrophysics than before. The emphasis is laid on Cepheids of all kind and RR Lyrae type variables, as well as binarity among pulsating variable stars.
