Sangeetha (சங்கீதா / सङ्गीता) is the Sanskrit and Tamil word for "music" — particularly the divine music of Saraswati.
Sangeetha Krish is the Indian Tamil actress. Carnatic music is called sangita.
Sangeetha does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Sangeetha reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
