# Frequency Ratio

### Some articles on frequency ratio, ratio, frequency:

Quarter-comma Meantone - Construction
... Thus, in Pythagorean tuning, where sequences of just fifths (frequency ratio 32) and octaves are used to produce the other intervals, a whole tone is and a major ... Pythagorean tuning, the size of a seventeenth is defined using a stack of four justly tuned fifths (frequency ratio 32) In quarter-comma meantone temperament, where a just major third (54) is ... Letting x be the frequency ratio of the flattened fifth, it is desired that four fifths have a ratio of 51, which implies that a fifth is a whole tone, built by moving two ...
Logrithm - Applications - Music
... In equal temperament, the frequency ratio depends only on the interval between two tones, not on the specific frequency, or pitch, of the individual tones ... For example, the note A has a frequency of 440 Hz and B-flat has a frequency of 466 Hz ... as is the one between B-flat and B (frequency 493 Hz) ...
Vibration Analysis - Forced Vibration With Damping
... states that the mass will oscillate at the same frequency, f, of the applied force, but with a phase shift The amplitude of the vibration “X” is defined by the following formula Where “r” is ... In a lightly damped system when the forcing frequency nears the natural frequency the amplitude of the vibration can get extremely high ... This phenomenon is called resonance (subsequently the natural frequency of a system is often referred to as the resonant frequency) ...
Cent (music) - Use
... Like a decibel's relation to intensity, a cent is a ratio between two close frequencies ... For the ratio to remain constant over the frequency spectrum, the frequency range encompassed by a cent must be proportional to the two frequencies ... An octave -- two notes that have a frequency ratio of 21 -- spans twelve semitones and therefore 1200 cents ...

### Famous quotes containing the words ratio and/or frequency:

Official dignity tends to increase in inverse ratio to the importance of the country in which the office is held.
Aldous Huxley (1894–1963)

One is apt to be discouraged by the frequency with which Mr. Hardy has persuaded himself that a macabre subject is a poem in itself; that, if there be enough of death and the tomb in one’s theme, it needs no translation into art, the bold statement of it being sufficient.
Rebecca West (1892–1983)
