Besides, what is the frequency of the note d?
When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of middle D (D4) is approximately 293.665 Hz. See pitch for a discussion of historical variations in frequency.
Secondly, what note is 220 Hz? For example, two tones whose frequencies are a factor of two apart are perceived as being the same musical note, although one is clearly higher than the other. These two notes are said to be one octave apart. Thus, for example, 440 Hz is the musical note A. So is 220 Hz and 880 Hz.
Hereof, what note is 60 Hz?
Since the electrical hum depends on the frequency of the current, so the sound will pretty much have the same frequency as the current. In the US, the current frequency is 60 Hz tone. The 60 Hz tone is almost exactly halfway between A♯ (58.24 Hz) and B (61.68 Hz).
What is the frequency of C?
261.63 Hz

D♭ (musical note) When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of middle D♭ (or D♭4) is approximately 277.183 Hz.To calculate the frequency of a wave, divide the velocity of the wave by the wavelength. Write your answer in Hertz, or Hz, which is the unit for frequency. If you need to calculate the frequency from the time it takes to complete a wave cycle, or T, the frequency will be the inverse of the time, or 1 divided by T.Any doubling of frequency corresponds to an octave increase in pitch, no matter what the initial frequency. 500 Hz corresponds (roughly) to the musical note B4, or the B above middle C, as shown on the piano keyboard. 1000 and 2000 Hz to B5 and B6.The D Major Scale. The notes of the D major scale are D – E – F# – G – A – B – C# – D. The note, D repeats one octave higher. Its key signature has two sharps.We will follow the International Standards Organization (ISO) system for register designations. In that system, middle C (the first ledger line above the bass staff or the first ledger line below the treble staff) is C4. An octave higher than middle C is C5, and an octave lower than middle C is C3.A440 (also known as Stuttgart pitch), or A4 in scientific pitch notation, is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C.In many countries the power fundamental frequency is 60 Hz, but for either 50 or 60 Hz it can be audible. You may hear the fundamental frequency or the second harmonic (100 or 120 Hz, respectively) and under some circumstances higher order harmonics may be audible as well.At its most basic, frequency is how often something repeats. In the case of electrical current, frequency is the number of times a sine wave repeats, or completes, a positive-to-negative cycle. Power line frequency (normally 50 Hz or 60 Hz).THE HISTORICAL REASON BEHIND 60Hz SYATEM USED IN USA. The use of 50 versus 60 Hz is purely due to historical reasons, with companies in the US making 60 Hz equipment and those in Europe making 50Hz equipment so that they have a monopoly. This rivalry led to the split you see today.E (musical note) - Wikipedia.Frequency is the speed of the vibration, and this determines the pitch of the sound. It is only useful or meaningful for musical sounds, where there is a strongly regular waveform. Frequency is measured as the number of wave cycles that occur in one second. The unit of frequency measurement is Hertz (Hz for short).The use of 50 versus 60 Hz is purely due to historical reasons, with companies in the US making 60 Hz equipment and those in Europe making 50Hz equipment so that they have a monopoly. This rivalry led to the split you see today.There is a term for an electrical buzzing sound which is referred to as mains hum. This is caused by an alternating current at the frequency of the mains. The sound often has substantial harmonic content at 50 / 60 hertz.Fundamental frequencies of Notes in Western Music

People can hear sounds at frequencies from about 20 Hz to 20,000 Hz, though we hear sounds best from 1,000 Hz to 5,000 Hz, where human speech is centered. Hearing loss may reduce the range of frequencies a person can hear. It is common for people to lose their ability to hear higher frequencies as they get older.Frequencies for equal-tempered scale, A4 = 440 Hz

The answer is simple. E# is the same as F. the reason we decided to call it F and not E sharp or G flat is because its just convention, we decided to name the notes of ONE of the scales simply, with the letters of the alphabet, no sharps or flats.The most intuitive answer is that "middle C" (or C4 in scientific pitch notation) is in the middle of the great staff. It's also on the middle line of the alto clef. As to why musicians most commonly refer to the letter C, that's because C is the starting note of the major scale which has no sharps or flats.Frequencies for equal-tempered scale, A4 = 440 Hz

We will follow the International Standards Organization (ISO) system for register designations. In that system, middle C (the first ledger line above the bass staff or the first ledger line below the treble staff) is C4. An octave higher than middle C is C5, and an octave lower than middle C is C3.Because when they decided to name the notes with letters, they took a minor scale and named the notes "naturally": A, B, C, D, E, F, G. This is what we know as the A minor scale. Now if we want to use the same "natural" notes in a major scale, then we need to start with C.Originally Answered: Why is middle c, middle c? The most intuitive answer is that "middle C" (or C4 in scientific pitch notation) is in the middle of the great staff. It's also on the middle line of the alto clef. And of course, it's the C key below the middle of a full 88-key keyboard.Because when they decided to name the notes with letters, they took a minor scale and named the notes "naturally": A, B, C, D, E, F, G.
