Vadi (music)

Vaadi, in both Hindustani classical music and Carnaatic music, is the tonic (root) swara (musical note) of a given raaga (musical scale). "Vaadi is the most sonant or most important note of a Raga."[1] It does not refer to the most played note but it rather refers to a note of special significance. It is usually the swara which is repeated the greatest number of times, and often it is the swara on which the singer can pause for a significant time. Vaadi swara in a raaga is like a king in a kingdom. The specialty of any raaga depends on vaadi swara and because of this, the vaadi swara is also called the Jeeva swara or the Ansha swara. A good artist uses vaadi swara in different ways like singing vaadi swara again and again, starting a raaga with vaadi swara, to end a raaga with vaadi swara, singing vaadi swara many times in important places with different swaras or sometime singing vaadi swara for a longer time in one breath.

Vaadi swara is also helpful to identify the appropriate time for singing or playing a raga. If the vaadi swara of a raaga is from the purvanga part of the saptak i.e. “Sa Re Ga Ma”, then it is called purvanga vaadi raaga and usually the time for singing or playing purvanga vaadi raagas is from 12 pm to 12 am. For example, ragas like Bhimpalasi, Pilu, Purvi, Marwa, Yaman, Bhoopali, and Bageshree etc. have purvanga vaadi swara and so the time for singing and playing these raagas is between 12 pm to 12 am.

In the same way, if the vaadi swara of a raaga is from the utraanga part of the saptak i.e. “Pa Dha Ni” then it is classed as a utraanga vaadi raaga and the time for singing or playing utraanga vaadi ragas is from 12 am to 12 pm. For example ragas like Bhairav, Bhairavi, Bilaa0wal, Kalingada, Sohini, and Asaavari etc. have utraanga vaadi swara and so the time for singing or playing these raagas is between 12 am to 12 pm.

Vaadi swara, along with the Samvaadi swara of a raga, usually brings out the uniqueness of the raaga and its bhaava (mood) and rasa (emotion).
