| Note | Frequency (Hz) | Wavelength (cm) |
|---|---|---|
| A4 | 440.00 | 78.41 |
| A#4/Bb4 | 466.16 | 74.01 |

Are pianos tuned to 440?
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.
Why is A 440 Hz?
In modern music, 440Hz has been established as the tuning standard. The pitch is that of A above middle C, and it provides a measure by which musicians can ensure their instruments will be in tune with others. In 1939, an international conference set the standard to 440, which is now known as “concert pitch.”
How does A real piano generate frequencies?
STRINGS. Every note sounded on a piano is the result of a string, or set of two or three strings, vibrating at a specific frequency (rate of traveling back and forth) determined by the length, diameter, tension and density of the wire.
What Hz is piano?
440 Hz
The fundamental frequencies for the notes on a piano range from 27.5 Hz to 4186 Hz. The modern standard for tuning defines the frequency of the note A above middle C to be 440 Hz. Musicians refer to this as “A-440.” It’s the reference frequency used for piano, guitar, and all band and orchestra instruments.
What Hz should I tune my piano to?
If you want to play popular music, and want to play it in tune, then you should use 440 Hz. In 1938 a conference in London decided that the tone A4 should have a frequency of 440 Hz.
What frequency is a piano?
27.5 Hz to 4186 Hz
What is the science behind a piano?
When you press a key on the piano it causes a small hammer inside the piano to hit a string or strings. Each key is connected to its own hammer or hammers which hit a specific string or number of strings. When the hammer hits a string, it vibrates and makes a sound that is tuned to a specific note.
What is the lowest Hz on a piano?
The lowest frequency on a piano is 27.5 Hz, which is almost at the start of the human hearing range.
