"Modal shift of tonic, also known as Graha Bhedam" refers to a technique in Carnatic music where the central pitch (tonic note) of a raga is shifted to a different note, essentially creating a new raga while maintaining the same relative positions of the other notes, allowing for a variation in mood and musical character; "Mohanam" is a specific raga often used to demonstrate this technique due to its melodic flexibility. 

Key points about Graha Bhedam:

• Meaning:

  "Graha" means "base" or "foundation" and "Bhedam" means "shift," so "Graha Bhedam" literally translates to "shifting the base note." 
• How it works:

  By moving the tonic note up or down within the raga, the musician creates a new melodic character while maintaining the same basic scale structure. 
• Improvisational element:

  This technique is often used in live performances as a way to add variety and depth to a raga by Subtly changing the mood through the shift in tonic.
