  2. Harmonic table note layout - Wikipedia

    en.wikipedia.org/wiki/Harmonic_table_note_layout

    The Harmonic Table keyboard layout was used in a keyboard harmonica called the Harmonetta, [2] invented by Ernst Zacharias [3] and manufactured by Hohner from the early 1950s through the mid-1970s. A similar keyboard was developed by Larry Hanson [ 4 ] in 1942 for use with a 53 tone scale but turns the fifth sideways and the major third to the ...

  3. Tetrachord - Wikipedia

    en.wikipedia.org/wiki/Tetrachord

    In music theory, a tetrachord (Greek: τετράχορδoν; Latin: tetrachordum) is a series of four notes separated by three intervals.In traditional music theory, a tetrachord always spanned the interval of a perfect fourth, a 4:3 frequency proportion (approx. 498 cents)—but in modern use it means any four-note segment of a scale or tone row, not necessarily related to a particular tuning ...

  4. Pythagorean tuning - Wikipedia

    en.wikipedia.org/wiki/Pythagorean_tuning

    Extended Pythagorean tuning corresponds 1-on-1 with western music notation and there is no limit to the number of fifths. In 12-tone Pythagorean temperament however one is limited by 12-tones per octave and one cannot play most music according to the Pythagorean system corresponding to the enharmonic notation.

    en.wikipedia.org/wiki/Inharmonicity

    Comparing harmonic (top) and inharmonic (bottom) waveforms. Percussion bars, such as xylophone, are hung at ≈2/9 and ≈7/9 length, and struck at 1/2 length, to reduce inharmonicity. In music, inharmonicity is the degree to which the frequencies of overtones (also known as partials or partial tones ) depart from whole multiples of the ...

  8. Beat (acoustics) - Wikipedia

    en.wikipedia.org/wiki/Beat_(acoustics)

    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, beats can be readily recognized.
