Step 1: Understanding the Concept:
The question asks for the specific name of the left-hand drum head of the Carnatic percussion instrument, the Mridangam. Step 2: Detailed Explanation:
The Mridangam is a double-sided drum.
- The right side, which is smaller, produces high-pitched, sharp sounds. It is called the 'Valanthalai'.
- The left side is larger and produces the bass sounds. This side is known as the 'Toppi'. A temporary paste of flour and water is often applied to the Toppi to lower its pitch and give it a rich bass tone.
The other terms refer to playing strokes. Step 3: Final Answer:
The left-hand side of the Mridangam is called the Toppi.
