Chakravakam or Chakravaham (pronounced chakravākam) is a rāgam in Carnatic music (musical scale in South Indian classical music). It is the 16th Melakarta rāgam (parent rāgam) in the 72 melakarta rāgam system. According to the Muthuswami Dikshitar school, this rāgam is called Tōyavēgavāhini. Chakravakam is close to Raga Ahir bhairav in Hindustani music.
Chakravakam is a raga that is known to incite feelings of devotion, sympathy and compassion in the listeners.
Structure and Lakshana
It is the 4th melakarta in the 3rd chakra Agni. The mnemonic name is Agni-Bhu. The mnemonic phrase is sa ra gu ma pa dhi ni. Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms):
The notes in this scale are shadjam, shuddha rishabham, anthara gandharam, shuddha madhyamam, panchamam, chathusruthi dhaivatham and kaisiki nishadham.
See List of Janya Ragas for a full list of its janyas.
Gajānanayutham is a popular composition in Tōyavēgavāhini, by the maestro Muthuswami Dikshitar, which is sung in a brisk tempo, unlike other compositions set to Chakravakam.
Film music has its share of popular compositions in Chakravakam/Ahir Bhairav which include songs such as "Albela Sajan" from "Hum Dil De Chuke Sanam" (Hindi), "Poochho Na Kaise Maine Rain Bitai" from "Meri Surat Teri Ankhen" (Hindi) and "Raakkili Than" from "Perumazhakalam" (Malayalam).
This section covers the theoretical and scientific aspect of this rāgam.
Chakravakam's notes when shifted using Graha bhedam, yields 2 other major melakarta rāgams, namely, Sarasangi and Dharmavati. Graha bhedam is the step taken in keeping the relative note frequencies same, while shifting the Shadjam to the next note in the rāgam. For an illustration refer Graha bhedam on Dharmavati.
