What is a Keerthanata? Asha describes the duet's title.
Asha, the composer of this new commission, describes her title as such:
"Keerthanata is a play on words combining the names for a standard form in South Indian classical music, keerthanam, with the Western musical term sonata. The melodic structure of Indian music known as raga often has a different ascending and descending form, often with zig-zags in the scalar pattern.The mode I invented for this piece models these aspects using all twelve pitches and employing complementary sets that lead to a wide array of characteristic chromatic gestures... Much of Indian classical music is highly emotional and serious, and this is also true of most of my music, but here I wanted to share the light, energetic aspect of Indian music and thereby infuse my own music with some frivolity!"
