The tonic. Fixed, unmoving, every other note is measured against it.
The second step. Can shift slightly flat or natural depending on the raga.
The third. Often the note that signals a raga's emotional colour.
The middle note. A hinge between the lower and upper half of the octave.
The fifth. Alongside Sa, it stays fixed across nearly every raga.
The sixth. Its raised or lowered form shapes the mood of the upper register.
The seventh. Leads the ear back toward Sa, closing the octave.
The octave above, the same note, returned to, an octave higher.
A raga gives sur its direction; taal gives it a place to land. Together they turn seven fixed notes into music that never repeats quite the same way twice.
