General Studies I
Consider the following statements :
1- A widely used musical scale called diatomic scale has seven frequencies.
2- The frequency of the note ‘Sa’ is 256 Hz and that of ‘Ni’ is 512 Hz.
Which of the statements given above is/are correct?
|C||Both 1 and 2|
|D||Neither 1 nor 2|
The “musical notes” is an “Interpreted Language”. The musicians read the notes, interpret them according to “Sa, Re, Ga, Ma…” or “Do, Re, Me… “ etc and play the instruments, what we get in output is musical sound waves. Think of a program which can take the Sa, Re, Ga, Ma etc and produce the sounds for the frequencies.
For Sa, the frequency is 256 Hz, similarly, for Re, it is 288Hz and for Ga, it is 320 Hz etc etc…
In Hindustani Classical Music, there are also intermediate Swars other than Shudh, Komal and Teevra Swars, e. g., Ati Komal Re and Anu Komal Re (I am not going into that).
Sa = 256 Hertz = C
Komal Re = 271 Hertz = C# (C-Sharp),
Shudh Re = 287 Hz = D, Komal Ga = 304 Hertz = D#,
Shudh Ga = 323 Hertz = E
Shudh Ma = 342 Hertz = F
Pa = 362 Hertz = F# Komal
Dha = 384 Hertz = G
Shudh Dha = 406 Hertz = G#
Komal Ni = 431 Hertz = A
Shudh Ni = 483 Hertz = Bb (B-Flat)
Higher Sa = 512 Hertz = C
