Sahana (raga)
Sahana (pronounced sahānā) or Shahana is a popular rāgam (musical scale) in Carnatic music. It is a janya rāgam (derived scale) associated with the 28th Melakarta rāgam Harikambhoji.
The Hindustani music ragam Sahana is an upper-tetrachord-dominant Kanada-anga raga, from the Kafi thaat, also allied with Bageshree and Bhimpalasi. The shuddha Dhaivat is an important rest note (nyaas swara).
