The Sanskrit text of Saṅgītaratnākara outlines the concepts of prastāra, saṅkhyā, naṣṭam and uddiṣṭam methods,
pātāla and mēru charts in a very terse and compact manner. The commentaries in various references, too, are not easy to comprehend.
These concepts are presented here in a simplified form and may be regarded as creative interpretations of the text. Some tables in the original text
have been recast after computational verification and for representational clarity.
