Triad - a special kind of chord, which is the main component of the harmonic part of any piece of music.Most often, this chord down to fit a certain way, so that it has a special sad or joyful color.The same technique as the treatment of triads, allows you to create new harmonies in the music, allows for a different emphases and gives the sound a new, more interesting and unique shade.
What is different from the rest of the triad chords
secret of this set of notes is in its name.This chord is made up of three sounds, one above the other on the movement of the staff.Most often it is based on thirds - large and small, but in some cases there are other ranges, such as the second, fourth, fifth or even sixth.Applications triads - this is the reason that every third can turn into a quart when transferring a single note one octave higher.Therein lies the secret of the beauty of sounding like every chord, and most importantly - for the same reason, in many cases it is easier to play, while not losing the basic sound and harmony of the work.
As the appeal to any chord
minimum chord may consist of three stages formed at different intervals.Assume that we are dealing with a standard major chord built from the notes "to", which includes the major and minor thirds.So, to make his first appeal, we have the lowest note that is "up", now taking an octave higher.It turns out that now our chord begins with the sound "E" and is already of a minor third and a perfect fourth.Applications triads are full, if we consider a third of them.In this case, an octave above already transferred note "E" and the chord is constructed with "G".Its structure will now be as follows: a perfect fourth and a major third.The name of these appeals are simple and come from the intervals at which to begin.The main chord - a tonic, its first appeal - tertskvartakkord, and the second - kvartterts.
Why triad and its treatment are considered the foundation of any melody
As already mentioned, each chord - is the main chord at any fret.The major or minor, in Dorian and Lydian harmony - the chord is built on three levels of scale.Thus, the tonic (as it is called harmony) begins with the first step fret, then it affects the third and fifth.The first note is considered to be the most stable, all the rest - auxiliary.Therefore, treatment of the tonic triad can be used for easy sorting in the accompaniment, the fundamental difference in the sound is not.An exception can be considered as those cases where the work ends at a certain chord.Tertskvart kvartterts and in such cases be unstable sound, in contrast to the tonic.
As modified by other chords
In theory and practice of music there are different kinds of triads, which may depend on a certain fret or be independent.This is a minor harmony, which is based on small and large third.Among the most common chords are also found an increase and decrease.They consist of either two thirds of large or small, respectively, of the two.Only in this case, that's triads treatment will be much more interesting.The enlarged lower chord when moving notes one octave higher we get a smaller quart.The sound of it is identical to the major third, the difference lies only in writing.Therefore, each treatment increased the chord is no different from its source.The smaller the lowest note, transposed up will form a larger quart or newt.The sound is sharp and specific, especially in combination with a minor third.
Other names appeals chords
Surely you've noticed that it was said, as if in a triad can contain not only short intervals such as thirds and a quart, but also very large - sixth.How do they fit into such harmony and how it affects the perception?In fact every call major triads contains this interval, namely its extreme form sounds.For example, the first variation of the tonic triad - it also sekstakkord, as depending on the major or minor frets his extreme notes can be the basis for a small or large sixth.The second appeal - it kvartsekstakkord.The major key to its extreme form already sounds great sixths, and in a minor key - small.
Why do I need to change the structure of the chord
Many beginning musicians do not always understand why the treatment is necessary major triads, if, in fact, from such metamorphoses are sound does not change.The answer to this question is the easiest way to get in the process of improvisation and composition.Sometimes even the same harmony, without deviations and auxiliary music signs, in one of his hits sound different.For example, you can often hear sekstakkord in developing or middle piece.It is not well founded, as a tonic, but at the same time gives the melody sustainability.Kvartsekstakkord considered introductory, that is after him will certainly need to play a tonic triad.
Conclusion
Similarly tonic chords of each modified scheme and adjacent subdominant and dominant.Often this method is used when you want to play the accompaniment spread out in the form of an arpeggio notes or simple search.This gives each product its charm and ambiguity, but at the same time leaves the possibility to preserve the unity of harmony.
