The concept of harmonic function originates in theories about just intonation.It was realized that three perfect major triads, distant from each other by a perfect fifth, produced the seven degrees of the major scale in one of the possible forms of just intonation: for instance, the triads F–A–C, C–E–G and G–B–D (subdominant, tonic, and dominant respectively) produce the seven ...
"All harmonic idioms in popular music are tonal, and none is without function." [4] [vague] Tonality is an organized system of tones (e.g., the tones of a major or minor scale) in which one tone (the tonic) becomes the central point for the remaining tones. The other tones in a tonal piece are all defined in terms of their relationship to the ...
Jaroslav Volek (15 July 1923, Trenčín – 23 February 1989, Prague) was a Czech musicologist, semiotician who developed a theory of modal music.His theory included ideas of poly-modality and alteration of notes that he called "flex," which result in what he called the system of flexible diatonics.
Monotonality is a theoretical concept, principally deriving from the theoretical writings of Arnold Schoenberg and Heinrich Schenker, that in any piece of tonal music only one tonic is ever present, modulations being only regions or prolongations within, or extensions of the basic tonality.
Euler's Tonnetz. The Tonnetz originally appeared in Leonhard Euler's 1739 Tentamen novae theoriae musicae ex certissismis harmoniae principiis dilucide expositae.Euler's Tonnetz, pictured at left, shows the triadic relationships of the perfect fifth and the major third: at the top of the image is the note F, and to the left underneath is C (a perfect fifth above F), and to the right is A (a ...
The tonal system, too, flows 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 .
In European art music, the common practice period was the period of about 250 years during which the tonal system was regarded as the only basis for composition. It began when composers' use of the tonal system had clearly superseded earlier systems, and ended when some composers began using significantly modified versions of the tonal system, and began developing other systems as well.
This notation indicates differing pitch, dynamics, articulation, instrumentation, timbre, and rhythm (duration and onset/order). Traditionally in Western music, a musical tone is a steady periodic sound.
