Combining Devanagari Digit Six

It marks Sāmavedic chant notation, not the number six.

Sāmaveda is the Vedic chant tradition. Its notation uses signs such as ꣦ to preserve cues for pitch, duration, and related vocal changes; this mark does not count objects.

A 1994 printed edition of Śrautakośa gives an early documented example. It shows that the sign was in use by then, not when it began.

Was ꣦ always the sixth tone?

No; that reading was challenged for the cited examples. The original encoding proposal called them atisvārya, or “sixth tone.” A 2015 review reported that Sāmavedic scholars read those examples as namana, a bending or sinking mode.

Unicode 17.0 lists “vaidika saamasvara namana” as an informative alias for the mark.

The wider Sāmavedic marker family includes combining digits, letters, and avagraha, a sign used in Sanskrit writing. Grantha script has a parallel set of chant-tone markers; the Jaiminīya branch of the Sāmaveda instead uses annotations between lines.
