Question

What is the frequency of the A4 and E5 notes in Pythagorean
temperament and Equal Temperament if C_{4} is 261.63

Answer #1

Hello,

The equal temperame C4 is 261.63 Hz, then the international tuning standard or the equal temperament scale of A4 is 440 Hz in Pythagorean temperament.

For E5 :

Musical intervals in terms of ratios are useful for pleasant sound.

According to the psychlogy of hearing, E5 is perfect 5th .

The ratio of fundamental frequencies for the interval between two pitches is 3:2. This is perfect 5th .

The expression is

The frequencies of A4 and E5 are 440 Hz and 660 Hz respectively.

Thanking You!

C" # has a frequency of 4,434.92 Hz in Equal Temperament Tuning.
In Just Intonation (tuned to A), the frequency of C" # is 4,400 Hz.
Find how many cents flatter the Just Intonation frequency of this
note is than the Equal Temperament Frequency of this note. Round to
the nearest cent.

You have invented a “septatonic” scale with 7 equally spaced
notes per octave (in the same sense as the equal-temperament
chromatic scale, which would be “dodecatonic” with 12 equally
spaced steps). What would be the frequency ratio between adjacent
notes? (in other words, what is the ratio between adjacent notes in
your ‘septatonic’ scale?)
0.1428
1.1041
1.0905
1.0000
1.1225

Suppose alleles A1,A2,A3, and A4 are additive in their effects,
and the homozygote fitnessesare A1A1: 0.8, A2A2: 0.6, A3A3: 0.4,
and A4A4: 0.2. What are the heterozygote fitnesses? I fall of the
alleles are of equal frequency, what is the mean fitness for this
locus?

Musical notes have names (A,B,C, etc). The lowest A on a piano
is called A0. If you go up an octave, the next A would be called
A1. An octave higher, A2. The A near the middle of the keyboard is
A4 (also called "concert A"). A similar pattern is true for all the
notes. In a certain set of organ pipes, the speaking length (that's
an effective physical length) for the pipe that makes the note E5
(f=660 Hz)...

a) At what frequency will the Inductive Reactance of 44. mH be
equal to the capacitive reactance of a 27.0 pF capacitor?
b) A 120.0 mH inductor is in series with a 20.0 Ω resistor in a

At what frequency would the wavelength of sound in air be equal
to the mean free path of oxygen molecules at 1.2 atm pressure and
-1.6°C? Take the diameter of an oxygen molecule to be 3.1 ×
10-8 cm and the speed of sound to be 340 m/s.

If the speed of the rotating magnetic field is equal to the
frequency of exerted current, what do you recommend for “braking”
of an AC machine if it is used as an electrical motor. What is the
normalized amplitude of the resultant magnetic field relative to
the magnetic field’s amplitude of each phase?

What beat frequency would be heard by a tuba player in a
marching band, of a note with a frequency of 4.50E2 Hz and the
notes echo off a stationary building; if he is walking towards the
building at a speed of 1.56 m/s, on a hot day with a temperature of
34.3 degC?
