Rhythm in Bharatanatyam is primarily used to convey emotions and moods. The intricate rhythmic patterns and variations help the dancer express a wide range of feelings, from joy and love to sorrow and anger.

Rhythmic patterns in Bharatanatyam are not always symmetrical. They can be asymmetrical, creating a sense of tension and release, or they can be repetitive, creating a sense of stability and grounding.

Tala is the basic unit of rhythm in Bharatanatyam. It is a rhythmic cycle that consists of a specific number of beats, arranged in a particular pattern.

There are seven commonly used talas in Bharatanatyam: Adi tala, Rupaka tala, Triputa tala, Chatusra tala, Khanda tala, Mishra tala, and Sankirna tala.

Adi tala is considered the most fundamental tala in Bharatanatyam. It consists of eight beats, arranged in a pattern of four plus four. It is often used for basic dance movements, such as adavus and jatis.

Adavu is a rhythmic pattern that is performed with the feet in Bharatanatyam. It is the basic building block of Bharatanatyam dance and is used to create intricate footwork and rhythmic variations.

There are 108 traditional adavus in Bharatanatyam, each with its own unique rhythmic pattern and footwork.

Drishti jati is not a type of jati in Bharatanatyam. Svara jati, pada jati, and hasta jati are the three main types of jatis, which are rhythmic patterns performed with the voice, feet, and hands, respectively.

Varnam is a rhythmic composition that is performed in Bharatanatyam. It is a complex and demanding piece that showcases the dancer's technical skill and artistry.

Varnams are not always performed in Adi tala. They can be performed in other talas as well, such as Rupaka tala or Triputa tala.

Thillana is a rhythmic composition that is performed at the end of a Bharatanatyam performance. It is a lively and energetic piece that showcases the dancer's rhythmic prowess and footwork.

Thillanas are not always performed in Adi tala. They can be performed in other talas as well, such as Rupaka tala or Triputa tala.
