Step 1: Concept
The Thillana (or Tillana) is a highly vibrant, joyful, and rhythm-oriented compositional form in Carnatic music. It is traditionally performed towards the end of a music concert, and serves as the brilliant finale in classical Bharatanatyam dance recitals.
Step 2: Structural Composition
Like most classical forms, it is structured into three sections:
1. Pallavi: Written entirely using catchy rhythmic syllables (solkattus) such as Dhi-rany, Thana-Dhirany, Thom-Thari-Thajanu.
2. Anupallavi: Continues the rhythmic syllables, usually traversing into higher octaves.
3. Charanam: Contains a short line of meaningful lyrics (sahitya) in praise of a deity, king, or patron, which immediately resolves into a fast, pre-composed rhythmic sequence (muktayi) of swaras and solkattus.
Step 3: Musical Characteristics
Thillanas are set to lively, sweet ragas (like Khamas, Behag, Hindolam, Kapi, Vasantha) and brisk, flowing talas (like Adi or Rupaka), producing a highly infectious, foot-tapping melody.
Final Answer: Thillana is a lively, rhythm-centric Carnatic composition featuring rhythmic syllables (solkattus) in the Pallavi and Anupallavi, and a short lyrical dedication (sahitya) in the Charanam. It is a staple of both music concerts and classical dance.
