Shadja is the first svara out of the seven svaras of Hindustani music and Carnatic music.[1] Shadja is the long form of the syllable सा.[2] For simplicity in pronouncing while singing the syllable, Shadja is pronounced as Sa (notation - S). It is also called as षड्ज in the Devanagri script.
The following is the information about Shadja and its importance in Indian classical music :
षड् - 6, ज -जन्म . Therefore, it collectively means giving birth to the other 6 notes of the music.
Consequently, the Sa after the Ni of 450 Hz has a frequency of 480 Hz i.e. the double of the Lower octave Sa.[citation needed]
For example, if these are the four Shruti's of Sa then,
Previously this was the position of the main Shruti of Sa. ^ 1 2 3 4 ^ But now this position has become the main Shruti of Sa.
