Careers of professional musicians are unique and their development cannot be fully generalized, as shown by interviews with instrument players and singers of classical music and musical in Slovakia. Their careers do not include all standard career stages; only three of them were identified in all respondents: preparation (tied with music education), active playing (associated with growth, peaks, crises, decrease) and career fading/extinction. The time limits of these stages cannot be set, as they considerably differ. Majority of musicians claim to overcome a professional crisis. A common feature of all respondents' careers is music teaching job at a certain point in their own careers

The article is devoted to the musical artefacts discovered on the territory of Slovakia. During the remotest ancient periods of time music served chiefly as a means for ceremonies, cults and magic rituals, and accompanied the process of work. Present-day perceptions about music in prehistorical times are formed from various types of evidence: archeological artifacts, pictures, carved figures and musical instruments. The most ancient of the latter are various rattles and pipes. An inherent part of musical activities was formed by dances and singing. Although there is an absence of direct evidence of the sound of the instruments, it may be presumed that during the first stages of the development of music one of its most important aspects was rhythm. Melodies were simple and consisted of few pitches with small intervals in between them, which comprised a basic motive, subsequently repeated numerous times.

Archaeological research in the territory of today’s Slovakia has revealed rare artifacts from the oldest period in human history, from prehistory. Two unique female figures of Venus represent them. This article presents a statuette from the Paleolithic Era — the Venus of Moravany, which is made from a mammoth tusk and is an artistic expression of fertility in the matriarchy. The article also describes a gem from the Neolithic period, the Venus of Hrádok, Magna Mater, as the goddess of harvest, success, the giver of life and well-being.
