Consider the following statements :
1. A widely used musical scale called diatonic scale has seven frequencies.
2. The frequency of the note Sa (सा) is 256 Hz and that of Ni (नी) is 512 Hz.
Which of the statements given above is/are correct?
Correct Answer: Option A
Explanation
1. Statement 1: The diatonic scale is a fundamental musical scale in Western music. It has seven distinct notes or pitch classes (e.g., C-D-E-F-G-A-B), corresponding to seven frequencies within one octave, before repeating. Statement 1 is correct.
2. Statement 2: In Indian classical music, 'Sa' and 'Ni' are notes (svaras) in the sargam scale. While 'Sa' is the tonic, its absolute frequency is not fixed at 256 Hz (which corresponds roughly to middle C in Western tuning); it depends on the chosen pitch standard (shruti) for the performance. Furthermore, 'Ni' is the seventh note, and its frequency relative to 'Sa' depends on the specific scale (thaat) being used; it is not necessarily double the frequency of 'Sa' (512 Hz would be the octave above Sa). Statement 2 is incorrect.
