Arohana is a term used in Indian classical music that refers to the ascending scale of a raga. It outlines the specific notes that are played or sung when moving upward in pitch. Each raga has its unique Arohana, which helps define its character and mood. In contrast, the descending scale is known as Avarohana. Together, these two components form the foundation of a raga, guiding musicians in their improvisation and composition. Understanding Arohana is essential for performers to convey the intended emotions and essence of the raga.
