Answer:
The frequency of the note a perfect fifth below C4 is;
B- 174.42 Hz
Step-by-step explanation:
Here we note that to get the "perfect fifth" of a musical note we have to play a not that is either 1.5 above or 1.5 below the note to which we reference. Therefore to get the frequency of the note a perfect fifth below C4 which is about 261.63 Hz, we have
1.5 × Frequency of note Y = Frequency of C4
1.5 × Y = 261.63
Therefore, Y = 261.63/1.5 = 174.42 Hz.
The frequency of the note a perfect fifth below C4 is 174.42 Hz
What is the perfect fifth?
The perfect fifth is a musical interval corresponding to a pair of pitches with a frequency ratio of 3:2, or very nearly so.
For the perfect fifth of a musical note,
we have to play a not that is either 1.5 above or 1.5 below the note to which we refer.
Therefore to get the frequency of the note a perfect fifth below C4 which is about 261.63 Hz,
We have
[tex]1.5 \times Frequency of note Y = Frequency of C4[/tex]
[tex]1.5 \times Y = 261.63[/tex]
divide both sides by 1.5
Y = 261.63/1.5 = 174.42 Hz.
Therefore we get, the frequency of the note a perfect fifth below C4 is 174.42 Hz.
