Janaki Bai had a voice with a terrific range, which could be heard from miles away, a voice not only powerful and deep but it was melodious and sonorous. The musicians of yesteryears used to say, “Janaki Bai ke kantha-swara me misri ghuli hui thi" (Janaki Bai's voice was sweet as sugar).
She received intensive music training from the famous Ustad Hassu Khan of Lucknow.
