  2. Harmonic table note layout - Wikipedia

    en.wikipedia.org/wiki/Harmonic_table_note_layout

    Harmonic table note layout. The Harmonic Table note-layout , or tonal array, is a key layout for musical instruments that offers interesting advantages over the traditional keyboard layout. Its symmetrical, hexagonal pattern of interval sequences places the notes of the major and minor triads together.

  3. Chart pattern - Wikipedia

    en.wikipedia.org/wiki/Chart_pattern

    A chart pattern or price pattern is a pattern within a chart when prices are graphed. In stock and commodity markets trading, chart pattern studies play a large role during technical analysis. When data is plotted there is usually a pattern which naturally occurs and repeats over a period. Chart patterns are used as either reversal or ...

  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.

  5. Rhythmic mode - Wikipedia

    Pérotin, "Alleluia nativitas", in the third rhythmic mode. In medieval music, the rhythmic modes were set patterns of long and short durations (or rhythms).The value of each note is not determined by the form of the written note (as is the case with more recent European musical notation), but rather by its position within a group of notes written as a single figure called a ligature, and by ...

  6. Bebop scale - Wikipedia

    en.wikipedia.org/wiki/Bebop_scale

    It contains all of the notes of both the harmonic minor scale and the natural minor scale (Aeolian mode) of the same root. It can be used on all three chords of a minor ii–V–I progression. It is the sixth mode of the bebop major scale: for instance, the C bebop harmonic minor scale has the same pitches as the E ♭ bebop major scale.

  7. Inharmonicity - Wikipedia

    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. Harmonic coordinates - Wikipedia

    en.wikipedia.org/wiki/Harmonic_coordinates

    The metric tensor relative to x is obtained from the metric tensor relative to y by a local calculation having to do with the first derivatives of x ∘ y −1, and hence the Christoffel symbols relative to x are calculated from second derivatives of x ∘ y −1. So both definitions of harmonic coordinates, as given above, have the qualitative ...

    Dominant seventh chord on C: C 7 Play ⓘ.. Jazz harmony is the theory and practice of how chords are used in jazz music.
