Well, it says the ratio 4/5, which maybe should be read 4:5. It doesn't say "to 4/5".berkeman said:
Okay! Yes, it's annoying when you get locked into a misreading like that.Mickey Tee said:
Changing the pitch in frequency ratio involves adjusting the frequency of a sound wave, which in turn affects the perceived pitch of the sound. A higher frequency will result in a higher pitch, while a lower frequency will result in a lower pitch.
The frequency ratio between two notes is directly related to the interval between those notes. For example, an octave has a frequency ratio of 2:1, meaning the higher note has twice the frequency of the lower note. Similarly, a perfect fifth has a frequency ratio of 3:2.
Pitch in frequency ratio is a relative measure, while pitch in hertz is an absolute measure. Frequency ratio compares the frequency of one note to another, while hertz measures the frequency of a note in cycles per second.
Yes, changing pitch in frequency ratio is commonly used in music production to create different musical effects or to transpose a song to a different key. It can also be used to tune instruments or to create harmonies.
In addition to frequency ratio, other factors that can affect the perceived pitch of a sound include amplitude, timbre, and the listener's perception. For example, a louder sound may be perceived as having a higher pitch, and a sound with a rich timbre may be perceived as having a lower pitch than the same note played on a different instrument.
