In Hindustani music, a Chalan is an extensive series of note patterns which summarises the development of a particular raga. It discloses the basic grammar of the raga and provides a treatment and melodic context of each tone.[1]
Chalan is the movement of a raga or development of a raga while performing Alap. It may also refer to a Pakad of a raga. (Note: Chalan is mostly similar to the Pakad of a raga)
For example, the Chalan of the Kedar (raga) is सा म ग प मे (tivra) म रे सा |
Beneath are some Chalans of different ragas for better understanding:
