Choral singing is an activity that contributes to human development and health, and at the same time enriches its social and cultural life. Choir singing has a positive effect on human physical and mental health and is important for developing empathy and sensitivity. In Croatia choral singing is very widespread and nurtured, as evidenced by numerous choral societies, associations, vocal groups, ensembles, choirs and choirs in cultural and educational institutions. The work deals with the portrayal of Petrinja as a city of culture in which the song and singing, choral singing, is strongly nurtured and promoted. Petrinja is a small town with a rich musical culture and tradition. The paper presents the history of the town of Petrinja and its cultural life, and above all the music life - how it started, the singing societies that were founded, the people who contributed greatly to the musical life of Petrinja, how it looks today, and the singing societies and choirs that operate today and continue to spread choral singing. The aim of the paper is to point out: the importance of choral singing and singing in general, the rich culture of choral singing in Croatia and the town of Petrinja, popularizing and expanding choral singing and developing an awareness of the cultural, artistic and traditional significance of choral singing.
