In Schenkerian analysis, the bass arpeggiation (German : Bassbrechung) is the bass pattern forming the deep background of tonal musical works. It consists in scale steps (de: Stufen) I-V-I, each of which may span hundreds of measures of music in the foreground. [2]

Schenkerian analysis is a method of analyzing tonal music, based on the theories of Heinrich Schenker (1868–1935). The goal is to demonstrate the organic coherence of the work by showing how it relates to an abstract deep structure, the Ursatz. This primal structure is roughly the same for any tonal work, but a Schenkerian analysis shows how, in an individual case, that structure develops into a unique work at the "foreground", the level of the score itself. A key theoretical concept is that of "tonal space". The intervals between the notes of the tonic triad in the background form a tonal space that is filled with passing and neighbour notes, producing new triads and new tonal spaces, open for further elaborations until the surface of the work is reached.

German language West Germanic language

German is a West Germanic language that is mainly spoken in Central Europe. It is the most widely spoken and official or co-official language in Germany, Austria, Switzerland, South Tyrol (Italy), the German-speaking Community of Belgium, and Liechtenstein. It is also one of the three official languages of Luxembourg and a co-official language in the Opole Voivodeship in Poland. The languages which are most similar to German are the other members of the West Germanic language branch: Afrikaans, Dutch, English, the Frisian languages, Low German/Low Saxon, Luxembourgish, and Yiddish. There are also strong similarities in vocabulary with Danish, Norwegian and Swedish, although those belong to the North Germanic group. German is the second most widely spoken Germanic language, after English.

In Schenkerian theory, a scale-step is a triad that is perceived as an organizing force for a passage of music. In Harmony, Schenker gives the following example and asserts that

The bass pattern is an arpeggiation in the sense that its middle note (V) first arises as the fifth of the elaborated chord (I), of which it is the upper-fifth divider. [3] It is only when it meets with the passing note Scale deg 2.svg of the fundamental line that V becomes an independent chord within the first one. [4] See also Schenkerian analysis, The arpeggiation of the bass and the divider at the fifth.

A broken chord is a chord broken into a sequence of notes. A broken chord may repeat some of the notes from the chord and span one or more octaves.

The bass arpeggiation properly speaking consists in the three scale steps I-V-I exclusively, but it may be elaborated at a remote level: see Schenkerian analysis, Elaboration of the bass arpeggiation.

In music theory, a leading-note is a note or pitch which resolves or "leads" to a note one semitone higher or lower, being a lower and upper leading-tone, respectively. Typically, the leading tone refers to the seventh scale degree of a major scale, a major seventh above the tonic.

Subdominant the fourth tonal degree of the diatonic scale, between the mediant and the dominant

In music, the subdominant is the technical name for the fourth tonal degree of the diatonic scale. It is so called because it is the same distance "below" the tonic as the dominant is above the tonic – in other words, the tonic is the dominant of the subdominant. It also happens to be the note immediately "below" the dominant. It is sung as fa in solfege. In the C major scale, the subdominant is the note F; and the subdominant chord uses the notes F, A, and C. In music theory, Roman numerals are used to symbolize the subdominant chord as 'IV' if it is within the major mode or 'iv' if it is within the minor mode.

In very much conventionally tonal music, harmonic analysis will reveal a broad prevalence of the primary harmonies: tonic, dominant, and subdominant, and especially the first two of these.

Chord (music) harmonic set of three or more notes

A chord, in music, is any harmonic set of pitches consisting of three or more notes that are heard as if sounding simultaneously.

Diminution

In Western music and music theory, diminution has four distinct meanings. Diminution may be a form of embellishment in which a long note is divided into a series of shorter, usually melodic, values. Diminution may also be the compositional device where a melody, theme or motif is presented in shorter note-values than were previously used. Diminution is also the term for the proportional shortening of the value of individual note-shapes in mensural notation, either by coloration or by a sign of proportion. A minor or perfect interval that is narrowed by a chromatic semitone is a diminished interval, and the process may be referred to as diminution.

Mediant the third scale degree of a diatonic scale, between the supertonic and the subdominant

In music, the mediant is the third scale degree of a diatonic scale, being the note halfway between the tonic and the dominant. It is sung as mi in solfege. Similarly, the submediant is halfway between the tonic and subdominant. The fifth note is almost always a perfect fifth, while the third note can equally be a minor or major third.

In music theory, a ninth chord is a chord that encompasses the interval of a ninth when arranged in close position with the root in the bass.

In music theory, a dominant seventh chord, or major minor seventh chord, is a seventh chord composed of a root, major third, perfect fifth, and minor seventh. It can be also viewed as a major triad with an additional minor seventh. When using popular-music symbols, it is denoted by adding a superscript "7" after the letter designating the chord root. For example, the dominant seventh chord built on G, written as G7, has pitches G–B–D–F:

In music theory, scale degree refers to the position of a particular note on a scale relative to the tonic, the first and main note of the scale from which each octave is assumed to begin. Degrees are useful for indicating the size of intervals and chords, and whether they are major or minor.

Voice leading is the linear progression of individual melodic lines and their interaction with one another to create harmonies, typically in accordance with the principles of common-practice harmony and counterpoint.

In music theory, prolongation is the process in tonal music through which a pitch, interval, or consonant triad is able to govern spans of music when not physically sounding. It is a central principle in the music-analytic methodology of Schenkerian analysis, conceived by Austrian theorist Heinrich Schenker.

The second inversion of a chord is the voicing of a triad, seventh chord, or ninth chord in which the fifth of the chord is the bass note. In this inversion, the bass note and the root of the chord are a fourth apart which traditionally qualifies as a dissonance. There is therefore a tendency for movement and resolution. In notation form, it is referred to with a c following the chord position or as a 6
4
chord.

Counterpoint is the second volume of Heinrich Schenker's New Musical Theories and Fantasies. It is divided into two "Books", the first published in 1910, and the second in 1922.

Fundamental structure underlying structure of a tonal musical work in Schenkerian analysis

In Schenkerian analysis, the fundamental structure describes the structure of a tonal work as it occurs at the most remote level and in the most abstract form. A basic elaboration of the tonic triad, it consists of the fundamental line accompanied by the bass arpeggiation. Hence the fundamental structure, like the fundamental line itself, takes one of three forms, according to which tonic triad pitch is the primary tone. The example hereby shows a fundamental structure in C major, with the fundamental line descending from scale degree :

The Urlinie offers the unfurling (Auswicklung) of a basic triad, it presents tonality on horizontal paths. The tonal system, too, flow into these as well, a system intended to bring purposeful order into the world of chords through its selection of the harmonic degrees. The mediator between the horizontal formulation of tonality presented by the Urlinie and the vertical formulation presented by the harmonic degrees is voice leading.

The upper voice of a fundamental structure, which is the fundamental line, utilizes the descending direction; the lower voice, which is the bass arpeggiation through the fifth, takes the ascending direction. [...] The combination of fundamental line and bass arpeggiation constitutes a unity. [...] Neither the fundamental line nor the bass arpeggiation can stand alone. Only when acting together, when unified in a contrapuntal structure, do they produce art.

In music, Roman numeral analysis uses Roman numerals to represent chords. The Roman numerals denote scale degrees ; used to represent a chord, they denote the root note on which the chord is built. For instance, III denotes the third degree of a scale or the chord built on it. Generally, uppercase Roman numerals represent major chords while lowercase Roman numerals represent minor chords ; elsewhere, upper-case Roman numerals are used for all chords. In Western classical music in the 2000s, Roman numeral analysis is used by music students and music theorists to analyze the harmony of a song or piece.

Linear progression

In music, a linear progression is a passing note elaboration involving stepwise melodic motion in one direction between two harmonic tones. "The compositional unfolding of a specific interval, one of the intervals of the chord of nature." For example: -- over the tonic. According to Schenker: "A linear progression always presupposes a passing note; there can be no linear progression without a passing note, no passing note without a linear progression." In German Zug may be combined with prefixes to create related words such as Untergreifzug, a linear progression rising from a lower voice, Uebergreifzug, a linear progression overlapping another, or Terzzug, linear progression through a third. The term Zug may best be translated as "a direct, unimpeded motion from one place to another."

Structural level a term for a structural level of a piece of music

In Schenkerian analysis, a structural level is a representation of a piece of music at a different level of abstraction, with levels typically including foreground, middleground, and background. According to Schenker musical form is "an energy transformation, as a transformation of the forces that flow from background to foreground through the levels."

Primary tone

In Schenkerian analysis, the primary tone or head tone is the starting tone of the fundamental line. The fundamental line itself originates as an arpeggiation of the tonic chord, filled by passing tones:
