  2. Monotonic function - Wikipedia

    en.wikipedia.org/wiki/Monotonic_function

    A function that is not monotonic. In mathematics, a monotonic function (or monotone function) is a function between ordered sets that preserves or reverses the given order. [ 1 ][ 2 ][ 3 ] This concept first arose in calculus, and was later generalized to the more abstract setting of order theory.

  3. Function (music) - Wikipedia

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

    Function (music) In music, function (also referred to as harmonic function[1]) is a term used to denote the relationship of a chord [2] or a scale degree [3] to a tonal centre. Two main theories of tonal functions exist today: The German theory created by Hugo Riemann in his Vereinfachte Harmonielehre of 1893, which soon became an international ...

  4. Riemannian theory - Wikipedia

    en.wikipedia.org/wiki/Riemannian_theory

    Riemannian theory, in general, refers to the musical theories of German theorist Hugo Riemann (1849–1919). His theoretical writings cover many topics, including musical logic, [1] notation, [2] harmony, [3] melody, [4] phraseology, [5] the history of music theory, [6] etc. More particularly, the term Riemannian theory often refers to his ...

  5. List of musical symbols - Wikipedia

    en.wikipedia.org/wiki/List_of_musical_symbols

    Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...

  6. Discontinuities of monotone functions - Wikipedia

    en.wikipedia.org/wiki/Discontinuities_of...

    Discontinuities of monotone functions. In the mathematical field of analysis, a well-known theorem describes the set of discontinuities of a monotone real-valued function of a real variable; all discontinuities of such a (monotone) function are necessarily jump discontinuities and there are at most countably many of them.

  7. Monotone convergence theorem - Wikipedia

    en.wikipedia.org/wiki/Monotone_convergence_theorem

    In the mathematical field of real analysis, the monotone convergence theorem is any of a number of related theorems proving the good convergence behaviour of monotonic sequences, i.e. sequences that are non- increasing, or non- decreasing. In its simplest form, it says that a non-decreasing bounded -above sequence of real numbers converges to ...

  8. Dirichlet–Jordan test - Wikipedia

    en.wikipedia.org/wiki/Dirichlet–Jordan_test

    Dirichlet–Jordan test. In mathematics, the Dirichlet–Jordan test gives sufficient conditions for a real -valued, periodic function f to be equal to the sum of its Fourier series at a point of continuity. Moreover, the behavior of the Fourier series at points of discontinuity is determined as well (it is the midpoint of the values of the ...

  9. Elements of music - Wikipedia

    en.wikipedia.org/wiki/Elements_of_music

    Elements of music. Music can be analysed by considering a variety of its elements, or parts (aspects, characteristics, features), individually or together. A commonly used list of the main elements includes pitch, timbre, texture, volume, duration, and form. The elements of music may be compared to the elements of art or design.
