There is actually an international standard here: called **International Pitch Notation (IPN)**, it labels Middle C as C4. An octave above Middle C is C5, an octave below Middle C is C3, etc.

## What is the octave below middle C called?

C3

An octave higher than middle C is C5, and an octave lower than middle C is **C3**. The tricky bit about this system is that the octave starts on C and ends on B.

## Which note is an octave above C?

note C5

In the diagram above, which depicts a C major scale, the music goes up from middle C, or C4 (the pitch C in the 4th octave on a piano) to the note **C5**, which is exactly one octave above it. The C4 vibrates at 261.63 Hz, and the C5 vibrates at 523.25 Hz—its sound waves are double the frequency of C4.

## How would you define an octave below a note?

octave, in music, an interval whose higher note has a sound-wave frequency of vibration twice that of its lower note. Thus the international standard pitch A above middle C vibrates at 440 hertz (cycles per second); the octave above this A vibrates at 880 hertz, while the octave below it **vibrates at 220 hertz**.

## What note is an octave above a?

For this reason, notes an **octave** apart are given the same note name in the Western system of music notation—the name of a note an octave above A is also A.

## WHAT IS a above middle C called?

**An octave** above Middle C is C5, an octave below Middle C is C3, etc.

## What is an octave above C1?

C1: **double pedal C**. C2: pedal C. C3: bass C. C4: middle C. C5: treble C.

## What is a middle C note?

Middle C is **the name given to the musical note C which is in the middle of the piano keyboard**. It is not actually quite the middle note of the keyboard, but very nearly, and of all the Cs on the piano it is the one nearest to the middle.

## What note is lower than C?

On a C scale, the notes from low to high would be **C, D, E, F, G, A, B, C**. But in a scale, some steps are larger than others. In a major scale, there are five whole steps and two half steps.

## What is C1 in music?

**The lowest C on the keyboard (the third white note from the end)** is called C1. From there, each C to the right increases by one, so next we have C2, then C3. Then comes middle C, or C4 (those two names are interchangeable).

## What is high C?

high C in British English

(haɪ siː ) noun. music. **the note two octaves above middle C, deemed to be a test of a singer’s ability**.

## What does 2 octaves mean?

Definition of double octave

: **a musical interval (see interval sense 2c) of two octaves** : fifteenth.

## What is the top note called?

Top notes. Top notes are otherwise called the **head notes**.

## What frequency is C 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.

Frequency of Middle C.

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

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

## What pitch is middle C?

Middle C (the fourth C key from left on a standard 88-key piano keyboard) is designated **C _{4}** in scientific pitch notation, and c′ in Helmholtz pitch notation; it is note number 60 in MIDI notation.

## What is C note music?

C, **third note of the musical alphabet**, and one which has always occupied a peculiarly distinctive position in that it is the keynote of what was once called the natural scale. Thus on the pianoforte it consists entirely of white notes and hence has come to be regarded as the simplest and most fundamental of all keys.

## What pitch is the note C?
