# Frequencies & Symbols

## The Frequencies

The following tables list various mathematical aspects of classical music scales, both Indian and Western. The 'Multiplier' values are fractions which, when multiplied to the frequency of the first note ( Sa or C ), give the value of frequency of specified note. For example, if the frequency of Sa is 240, then by the table we have

Multiplier of Ma (F) = 4/3

Frequency of Ma (F) = 4/3 x Frequency of Sa (C) = 4/3 x 240 = 320

The mutual distances are relative ratios of frequencies of two notes. These are calculated by dividing the frequencies of the notes. For example, the mutual distance between Ma (F) and Pa (G) is

Frequency of Pa (G) = 360

Frequency of Ma (F) = 320

Mutual Distance between Pa and Ma = 360/320 = 9/8
