A fourth feature is the ambiguity that arises from the use of the same terms to describe fictions across all temporal spans ofa hierarchical structure from the surface to the deepest level, and that the longer term or deeper fimctions act as a center for shorter higher level ones and that the fimctions of each tend to counteract each other.31 "Harmonic fimction essentially results from the judgment that certain chords and tonal combinations sound and behave alike, even though these individuals might not be analyzed into equivalent harmonic classes," for example V and VII.) "Harmonic fiction is more about...similarity than equivalence’ [4] Pandiatonic music is diatonic music without the use of diatonic functions.

His main idea was to create a comprehensive theoretical basis for understanding the principles of harmonic relationships typical for the Baroque, Classical and Romantic periods. His work had huge impact, especially where German influence was strong. A good example in this regard are the textbooks by Hermann Grabner.[51[61 Riemann's basic theories have since been adopted, refined and elaborated upon by many authors of textbooks in harmony, arranging and composition, Functional harmony is being taught as a basic discipline in music theory all over the westem world, though different labels are used. Other terms used in the English and American tradition include Common Practice Harmony (stemming from Walter Piston!”}), Tonal harmony (as used by Allen Forte!) and Traditional harmony (as used by Gordon Delamont.!°] Vincent Persichetti'!l describes the 19th- century harmonic repertoire as "chords evolving around the tonic pillars" (tonic, subdominant, dominant), Nonfunctional harmony, the opposite of fictional harmony, is harmony whose progression is not guided by function, Diatonic functions of notes and chords ii iii WV Vi vi vit The seven scale degrees in C major with their respective triads and Roman numeral notation Each degree of a diatonic scale, as well as each of many chromatically-altered notes, has a different diatonic fimction as does each chord built upon those notes. A pitch or pitch class and its enharmonic equivalents have different meanings. For example, a C# cannot substitute for a Db, even though in equal temperament they are identical pitches, because the D> can serve as the minor third ofa Bb minor chord while a C# cannot, and the C2 can serve as the fiflh degree of an F# major scale, while a D> cannot. In music theory, as itis commonly taught in the US, there are seven different functions. In Germany, from the theories of Hugo Riemann, there are only three, and fimetions other than the tonic, subdominant and dominant are called their "parallels" (US: "relatives"). See Functional harmony. For instance, in the key of C major, an A minor envwiipesaorgi/Ditoniefncton 28aaa Diatoic teen - Wiad to feo oneetpadia (chord, scale, or, sometimes, the note A itself) is the Tonic parallel, or Tp. (German musicians use only uppercase note letters and Roman numeral abbreviations, while in the US, upper- and lowercase are usually used to designate major or augmented, and minor or diminished, respectively.)!!") In the US, it would be referred to as the "relative minor’ As d'Indy summarizes: 1. There is only one chord, a perfect chord; it alone is consonant because it alone generates a feeling of repose and balance; 2. this chord has two different forms, major and minor, depending whether the chord is composed ofa minor third over a major third, or a major third over a minor; 3. this chord is able to take on three different tonal functions, tonic, dominant, or subdominant. —D'Indy (1903), (121 In the United States, Germany, and other places the diatonic fimctions are: Function Rome English German Corman oon Tonic I Tonic Tonika T Supertonic i Subdominant parallel Subdominanten-Parallele | Sp Mediant i patel ParaleVTonie Counter 1) inanten-Parallele Dp/Tkp Subdominant IV Subdominant Subdominante s Dominant | V Dominant Dominante D Submediant vi Tonic parallel Tonika-Parallele verkiiraer Dominant-Sept- Leading vil incomplete Dominant seventh Wy Note that the i, i, vi, and vii are lowercase; this is because in relation to the key, they are minor chords.

The parallel is formed by raising the fit a whole tone; the root position of the parallel chords is indicated by the small noteheads. Functions in the minor mode Main article: Contrast chord Inthe US the minor mode or scale is considered a variant of the major, while in German theory itis often considered, per Riemann, the inversion of the major. In the late 18th and early 19th centuries a large number of symmetrical chords and relations were known as "dualistic" harmony. The root ofa major chord in root position is its bass note, but, symmetrically, the 'root! of a minor chord in root position is the fifth (for example CEG and ACE). The plus and degree symbols, + and ®, are used to denote that the lower tone of the fifth isthe root, as in major, +4, or the higher, as in minor, °d. Thus, ifthe major tonic parallel is the tonic, with the fifth raised a whole tone, then the minor tonic parallel is the tonic with the US root/German fifth Jowered a whole tone.l!!] Major Minor Parallel Note letter in CUS name | Parallel Note letter in CUS name Tp Aminor Submediant tP E> major Mediant Sp Dmminor Supertonic | sP Ab major Submediant Dp E minor Mediant dP ‘Bb major Subtonic ro The minor tonic, subdominant, dominant, and their parallels, created by lowering the fifth (German)/root (US) a whole tone. Ifchords may be formed by raising (major) or lowering (minor) the fifh a whole step, they may also be formed by lowering (major) or raising (minor) the root a half-step to wechsel, the leading tone or leitton. These chords are Leittonwechselkliinge (literally: "eading-tone changing sounds"), sometimes called gegenklang or "contrast chord" (4) envihipsca.orgkiDiatonie functioneats Diatonic farcion - Wiipoda, tree encyclopedia Leittonwechselklinge Mode Key _ Position Eminor TI Major A minor | SI Bminor DI Ab major tL Minor Db major sL E> major dL. oo Major Leittonwechselkkinge, formed by lowering the root a half step Minor Leittonwechselkkinge, formed by raising the root (US)/fifh (German) a half'step Quotes ‘Three categories can appear in any one of three chordal guises in either of two modes, eighteen positions in alt T, Tp, TI, t, tP, tL, S, Sp, SI, s, sP, sL, D, Dp, Dl, d, dP, dL. Why all this complexity? Perhaps the central reason is that this ingenious, occasionally convoluted system enabled Riemann to achieve a grand and masterful synthesis of both the old and the new in late 19th-century music. Ostensibly remote triads could be interpreted through the traditional terms of the I-IV-V-I, or now T- S-D-T, cadential schema. A sequence of Ab-major, B>-major, and C-major chords, for example, could be neatly interpreted as a subdominant (sP) to dominant (dP) to tonic (T) progression in C- major, a reading of these chords not without support in certain late-Romantic cadences. And a chord that often perplexes harmony students, the Neapolitan chord Db major in a C-major context, could be shown to be nothing more than a minor-mode subdominant Leittonwechselklang (sL). —Carl Dahihausl!!] Some may at first be put off by the overt theorizing apparent in German harmony, wishing perhaps that a choice be made once and for all between Riemamn's Funktionstheorie and the older Stufentheorie, or possibly believing that so-called linear theories have settled all earlier disputes. Yet this ongoing conflict between antithetical theories, with its attendant uncertainties and complexities, has envihipsca.orgkiDiatonie functionaaa Diatoictuecton -Wiipoda to feo oneetpodia special merits, In particular, whereas an English-speaking student may falsely believe that he or she is Jeaming harmony "as it really is," the German student encounters what are obviously theoretical constructs and must deal with them accordingly. —Carl Dahlhausl!!] Circle of fifths Another theory regarding harmonic functionality is that "fimctional succession is explained by the circle of fifths (in which, therefore, scale degree II is closer to the dominant than scale degree IV)." According to Goldman's Harmony in Western Music") "the 1V chord is actually, in the simplest mechanisms of diatonic relationships, at the greatest distance from I, In terms of the circle of fifths, it leads away from I, rather than toward it." Thus the progression I-i-V-I would comply more with tonal logic. However, Goldman,!!3] as well as Jean-Jacques Nattiez, points out that "the chord on the fourth degree appears long before the chord on II, and the subsequent final I, in the progression I-IV-vii?-iii-vi-i-V-1." 14] Goldman also points out that, "historically the use of the IV chord in harmonic design, and especially in cadences, exhibits some curious features. By and large, one can say that the use of IV in final cadences becomes more common in the 19th century than it was in the 18th, but that it may also be understood as a substitute for the ii chord when it precedes V. It may also be quite logically construed as an incomplete ii” chord (lacking root)."!'3] However, Nattiez calls this, "a narrow escape: only the theory of a ii chord without a root allows Goldman to maintain that the circle of fifths is completely valid from Bach to Wagner." ['4] Tonicization and modulation Functions during or after modulations, and especially tonicizations, are offen notated in relation to the funetion—in the original key—of the chord being tonicized. For example, in C major, a D major chord is notated as Il, but during a tonicization of a G major chord, it would be notated as it is finctioning in G major but with the G also notated as it functions as the dominant of C major. The standard notation for this is: V/V (five of five). For example, the twelve bar blues tumaround, I-V-IV-I, considered tonally inadmissible, may be interpreted as a doubled plagal cadence, IV/V-V-IV-I (IV/V-L/V, IV/-V/D. Functional behaviours From the viewpoint of musical behaviour or structure there are three essential functions: 3 essential functions Chord Inversion Tonic 1 Dominant vii IV Predominant ii Other fimctions serve to support the Tonic and Dominant fimetions listed above: = Dominant preparation envihipsca.orgkiDiatonie function caeats Dietonic futon - Whipoda, te ree encyclopedia = Tonic substitution or extension The dominant, dominant preparation and the tonic substitution all involve more than one scale degree with only the tonic and subdominant containing only one scale degree. Several scale degrees exercise more than one fiction.) The tonic includes four separate activities or roles as the: * Principal goal tone or event = Initiating event = Generator of other tones, and the = Stable center neutralizing the tension between dominant and subdominant, while the dominant has only the role of creating instability that requires the tonic or goal-tone for release. The subdominant also acts as a dominant preparation. A tonic extension is an elaboration of an initiating event while substitution is an alteration of a cadential point or goal tone. Many of these fimctions may still be found in post-tonal music] See also = Common practice period * Constant structure * Diatonic and chromatic * Nondominant seventh chord = Secondary dominant = Subsidiary chord = Roman numeral analysis Further reading = Inmig, Renate (1970).
