Part Two — The Music
What the Chant Actually Is
Sapta Svara — the Seven Notes
Indian classical music — both Hindustani and Carnatic — is built on seven notes: Sa, Re, Ga, Ma, Pa, Dha, Ni. These are the sapta svara, the seven syllables. Every raga in the tradition, every composition, every alap and every kriti, draws its melodic vocabulary from these seven. They are to Indian music what the seven-note diatonic scale is to Western music — the alphabet from which everything else is built.
The seven notes are not Indian classical music’s invention. They are the Sama Veda’s. The line from the chants of the Sama Veda to the seven svaras of every raga sung today is unbroken, and it can be traced with some exactness.
The earliest Vedic chant — what the Rig Veda was reciting — used only three tones, called udatta (raised), anudatta (lowered), and svarita (a falling glide between them). Three tones are enough to mark accent and meter; they are not enough for music. The chant that preserves only the three-tone system sounds, to a modern ear, somewhere between speech and song — controlled, severe, but not melodic.
The Sama Veda is what happened when those three tones were no longer enough. The Udgatris, singing the same Rig Vedic verses but in liturgical contexts that demanded longer, more developed melodies, expanded the system. They added intermediate tones. They added a tone above the udatta and a tone below the anudatta. They eventually arrived at seven distinct pitches — and they named them.
The Sama Vedic names for the seven notes were not yet Sa Re Ga Ma Pa Dha Ni. They were Krushta (the highest), Prathama (first), Dvitiya (second), Tritiya (third), Chaturtha (fourth), Mandra (low), and Atisvara (very low). The notation in Sama Vedic manuscripts uses a simple system — a numeral above each syllable showing which of the seven tones to pitch it at, sometimes with additional marks for ornament. The Naradiya Shiksha, an ancient text on Vedic phonetics, gives the mapping between the seven Sama Vedic names and the seven svaras of music — and the mapping is precise. Prathama corresponds to Ga, Dvitiya to Re, Tritiya to Sa, Chaturtha to Ni, and so on; the Sama Vedic scale is, in effect, the descending classical scale.
Why descending? Because the Vedic chant moved downward from the highest tone, while later Indian music conventionally ascends from Sa. The pitches are the same; the direction of melodic motion is reversed. The interval structure — what later musicians would call shadja-grama, the natural scale — is recognisably the seven-note scale from which the classical tradition would build the raga system.
This is the first written-down musical scale in the human record. The Greek modal system was developed later. The Chinese pentatonic system existed in parallel but was not notated in this way. The Sama Vedic notation — a numeral above each syllable, marking which of seven pitches to sing — is the earliest surviving musical score.
The seven svaras you can hear in a raga today, in any concert hall in Chennai or Calcutta or Kolhapur, are the same seven that an Udgatri sang in the soma sacrifice three thousand years ago. The melody he sang is gone. The grammar of pitches he used is not. The Sama Veda is why Indian classical music sounds the way it sounds.
