  2. 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.

  3. 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.

  4. 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 ...

    Set 3-1 has three possible versions: [0 1 1 1 2 T], [0 1 1 T E 1], and [0 T T 1 E 1], where the subscripts indicate adjacency intervals. The normal form is the smallest "slice of pie" (shaded) or most compact form, in this case: [0 1 1 1 2 T ].

  6. Harmonic scale - Wikipedia

    en.wikipedia.org/wiki/Harmonic_scale

    Harmonic series on G, partials 1–5 numbered Play ⓘ. The harmonic scale is a "super-just" musical scale allowing extended just intonation, beyond 5-limit to the 19th harmonic (Play ⓘ), and free modulation through the use of synthesizers. Transpositions and tuning tables are controlled by the left hand on the appropriate note on a one ...

    en.wikipedia.org/wiki/Digital_pattern_generator

    Digital pattern generators are today available as stand-alone units, add-on hardware modules for other equipment such as a [logic analyzer] or as PC-based equipment.. Stand-alone units are self-contained devices that include everything from the user interface to define the patterns that should be generated to the electronic equipment that actually generates the output signal.

  8. Contraharmonic mean - Wikipedia

    en.wikipedia.org/wiki/Contraharmonic_mean

    It is not monotonic − increasing a value of can decrease the value of the contraharmonic mean. For instance C(1, 4) > C(2, 4).. The contraharmonic mean is higher in value than the arithmetic mean and also higher than the root mean square: ⁡ ⁡ ⁡ ⁡ ⁡ ⁡ () where x is a list of values, H is the harmonic mean, G is geometric mean, L is the logarithmic mean, A is the arithmetic mean, R ...

  9. Harmonic balance - Wikipedia

    en.wikipedia.org/wiki/Harmonic_balance

    Harmonic balance is a method used to calculate the steady-state response of nonlinear differential equations, [1] and is mostly applied to nonlinear electrical circuits. [ 2 ] [ 3 ] [ 4 ] It is a frequency domain method for calculating the steady state, as opposed to the various time-domain steady-state methods.
