  2. Tuning fork - Wikipedia

    en.wikipedia.org/wiki/Tuning_fork

    Tuning fork pitch varies slightly with temperature, due mainly to a slight decrease in the modulus of elasticity of steel with increasing temperature. A change in frequency of 48 parts per million per °F (86 ppm per °C) is typical for a steel tuning fork. The frequency decreases (becomes flat) with increasing temperature. [6]

  4. Sympathetic resonance - Wikipedia

    en.wikipedia.org/wiki/Sympathetic_resonance

    Sympathetic resonance has been applied to musical instruments from many cultures and time periods, and to string instruments in particular. In instruments with undamped strings (e.g. harps, guitars and kotos), strings will resonate at their fundamental or overtone frequencies when other nearby strings are sounded.

  5. Piano key frequencies - Wikipedia

    en.wikipedia.org/wiki/Piano_key_frequencies

    For other tuning schemes, refer to musical tuning. This list of frequencies is for a theoretically ideal piano. On an actual piano, the ratio between semitones is slightly larger, especially at the high and low ends, where string stiffness causes inharmonicity, i.e., the tendency for the harmonic makeup of each note to run sharp.

    Diagram of beat frequency. In acoustics, a beat is an interference pattern between two sounds of slightly different frequencies, perceived as a periodic variation in volume whose rate is the difference of the two frequencies. With tuning instruments that can produce sustained tones

  7. Piano tuning - Wikipedia

    en.wikipedia.org/wiki/Piano_tuning

    An A440 tuning fork A common method of tuning the piano begins with tuning all the notes in the "temperament" octave in the lower middle range of the piano, usually F3 to F4. A tuner starts by using an external reference, usually an A440 tuning fork , (or commonly a C523.23 tuning fork) to tune a beginning pitch, and then tunes the other notes ...

  9. A440 (pitch standard) - Wikipedia

    en.wikipedia.org/wiki/A440_(pitch_standard)

    A440 (also known as Stuttgart pitch [1]) 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, or A 4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16.
