## What frequency is A below middle C?

Frequency of Middle C

A-almost-an-octave-above-middle-C is at | 440 Hz |
---|---|

Lower one octave to B-immediately-below-middle-C | 495/2=247.5Hz |

Raise a fifth to F-immediately-above-middle-C | 247.5(3/2)=371.25 Hz |

Lower an octave to F-below-middle-C | 371.25/2=185.625 Hz |

Raise a fifth to Middle C | 185.625(3/2)=278.4375 Hz |

## What frequency is an A flat?

Designation by octave

Scientific designation | Helmholtz designation | Frequency (Hz) |
---|---|---|

A♭0 | A♭͵͵ or ͵͵A♭ or AAA♭ | 25.957 |

A♭1 | A♭͵ or ͵A♭ or AA♭ | 51.913 |

A♭2 | A♭ | 103.826 |

A♭3 | a♭ | 207.652 |

**What note is 500hz?**

trumpet

Frequency is directly proportional to pitch. Higher the frequency, higher the pitch. Hence, trumpet has the highest frequency of 500 Hz, and highest pitch.

**How many Hz is middle A?**

440 Hz

In 1953, a worldwide agreement was signed. Signatories declared that middle “A” on the piano be forevermore tuned to exactly 440 Hz. This frequency became the standard ISO-16 reference for tuning all musical instruments based on the chromatic scale, the one most often used for music in the West.

### What is below middle C?

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.

### WHAT IS A below middle C called?

The C notes immediately below and above middle C are called Bass C and Treble C respectively. The next lower and higher C keys are called low C and high C.

**What is the frequency of note C?**

Historically, concert pitch has varied. For an instrument in equal temperament tuned to the A440 pitch standard widely adopted in 1939, middle C has a frequency around 261.63 Hz (for other notes see piano key frequencies).

**Why is middle C 256 Hertz?**

Since 256 is a power of 2, only octaves (factor 2:1) and, in just tuning, higher-pitched perfect fifths (factor 3:2) of the scientific pitch standard will have a frequency of a convenient integer value.

## What Hz is 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.

## What note is C6?

Even there, the C note is C6.

**What note is 60hz?**

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). However, the 60 Hz frequency is pretty much only used in the Americas (mostly), Saudi Arabia, South Korea, the Philippines and about half of Japan.

**What is C5 in music?**

C 5th chord Explanation: The C fifth is a two-note chord (since no third is included, it is neither a major nor minor chord). The chord is abbreviated C5. Theory: The C5 chord is constructed with a root and a fifth. It is common to also include the first note again one octave up.

### What is the frequency of Middle a above middle C?

The middle A, above middle C, has a frequency of 440 Hz. To find the frequency of a note an octave higher the frequency is doubled. To find the frequency of a note one octave lower the frequency is halved. Frequency can also go in fifths by using the formula x (3/2) = y where x is the original note and y is the fifth note above the original.

### What is the frequency of the note E ♭ above middle C?

When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the E ♭ above middle C (or E ♭4) is approximately 311.127 Hz. See pitch (music) for a discussion of historical variations in frequency.

**Which is a perfect fourth above middle C?**

E ♭ is a perfect fourth above B♭, whereas D ♯ is a major third above B . When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the E ♭ above middle C (or E ♭4) is approximately 311.127 Hz. See pitch (music) for a discussion of historical variations in frequency.

**How to calculate the frequency of a 4?**

Examples using A 4 = 440 Hz: C 5 = the C an octave above middle C. This is 3 half steps above A 4 and so the frequency is f 3 = 440 * (1.059463..) 3 = 523.3 Hz
