Vachaspati's notes when shifted using Graha bhedam, yields 3 other major melakarta rāgams, namely, Charukesi, Gourimanohari and Natakapriya. Graha bhedam is the step taken in keeping the relative note frequencies same, while shifting the Shadjam to the next note in the rāgam.

Vachaspati corresponds to the Acoustic scale in Western music.
