The harmonium, a vital component of Indian music, has ingrained itself in the cultural and musical history of the country. Originating in the West, the harmonium made its way to India during the colonial period and underwent a captivating evolution. Locally referred to as the “peti” or “baja,” it became an essential element in traditional Indian music, especially in classical, devotional, and folk genres. The unique sound produced by its bellows and reeds complements both vocal and instrumental performances, contributing a harmonious resonance to compositions. The harmonium’s versatility and compatibility with Indian melodies have firmly established its status as a cherished and indispensable instrument in the musical landscape of India.
