#30DayMarghazhiRagaChallenge - Desh
Desh - another Hindustani raga that has been wonderfully homogenized into the Carnatic system. Desh or Des is quite easily identifiable owing to its double nishadha and of course every Indian will recognize Desh from Vande Mataram! The aarohana contains kakali nishadha whereas the avarohana features kaishiki nishadha. Being a janya raga of 28th Melakarta Harikambhoji, the kakali nishadha can be considered a bhashanga swara (or foreign note). The nishadhas are often used by artists to bring out the beauty of the raga. Phrases demonstrating the two nishadhas, such as "MPN2-DP" - "MPN3S" particularly point to the bhashanga nature. Other common phrases include "RMP", "N2DP", "RMPN3" etc.

I haven't come across any composition in the raga Desh by the musical trinity so far, but would be happy to know if anything exists. Other than that, compositions in various South Indian languages in Desh are extremely prevalent. Rama namame in Tamil, composed by Shri Tanjavur Shankar Iyer, the famous Raghupati Raghava Rajaram, Hey Govinda Hey Gopala, in Hindi, composed by Shri Surdas are all in Desh.
