  3. Gamma wave - Wikipedia

    en.wikipedia.org/wiki/Gamma_wave

    A gamma wave or gamma rhythm is a pattern of neural oscillation in humans with a frequency between 30 and 100 Hz, the 40 Hz point being of particular interest. [1] Gamma rhythms are correlated with large-scale brain network activity and cognitive phenomena such as working memory , attention , and perceptual grouping , and can be increased in ...

  4. Piano key frequencies - Wikipedia

    en.wikipedia.org/wiki/Piano_key_frequencies

    This is a list of the fundamental frequencies in hertz (cycles per second) of the keys of a modern 88-key standard or 108-key extended piano in twelve-tone equal temperament, with the 49th key, the fifth A (called A 4), tuned to 440 Hz (referred to as A440). [1] [2] Every octave is made of twelve steps called semitones.

  5. Harmonic series (music) - Wikipedia

    en.wikipedia.org/wiki/Harmonic_series_(music)

    This objective structure is augmented by psychoacoustic phenomena. For example, a perfect fifth, say 200 and 300 Hz (cycles per second), causes a listener to perceive a combination tone of 100 Hz (the difference between 300 Hz and 200 Hz); that is, an octave below the lower (actual sounding) note. This 100 Hz first-order combination tone then ...

  6. Audio frequency - Wikipedia

    en.wikipedia.org/wiki/Audio_frequency

    The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz. [2] [3] [4] In air at atmospheric pressure, these represent sound waves with wavelengths of 17 metres (56 ft) to 1.7 centimetres (0.67 in).

  7. Heinrich Hertz - Wikipedia

    Heinrich Rudolf Hertz (/ h ɜːr t s /, HURTS; German: [ˈhaɪnʁɪç hɛʁts]; [1] [2] 22 February 1857 – 1 January 1894) was a German physicist who first conclusively proved the existence of the electromagnetic waves predicted by James Clerk Maxwell's equations of electromagnetism. The SI unit of frequency, the hertz (Hz), is named after ...

  8. Fundamental frequency - Wikipedia

    en.wikipedia.org/wiki/Fundamental_frequency

    Vibration and standing waves in a string, The fundamental and the first six overtones. The fundamental frequency, often referred to simply as the fundamental (abbreviated as f 0 or f 1), is defined as the lowest frequency of a periodic waveform. [1] In music, the fundamental is the musical pitch of a note that is perceived as the lowest partial ...

    This chakra can also be activated by chanting the Seed-Mantra. It is said that one who chants the Seed Mantra of Muladhara Chakra for more than 100,000,000 times can attain all the Siddhis of the Muladhara Chakra. [citation needed] There are also special meditation practices for awakening the Mūlādhāra Chakra. [9]
