Triad is a special kind of chord, which is the main component of the harmonic part of any musical work. Most often, this chord is tuned to a certain mood, so it has a special sad or joyful color. The same technique as reversing triads allows you to create new harmonies in music, makes it possible to put emphasis in a different way and gives the sound a new, more interesting and unique shade.
What is the triad different from other chords
The secret to this set of notes lies in its very name. This chord consists of three sounds located one above the other along the movement of the musical staff. Most often, it is based on thirds - large and small, but in some cases there are other intervals, such as seconds, quarts, fifths and even sixths. The reversal of triads is the reason why each third can turn into a quart when you transfer one note an octave higher. This is the secret of the beauty of the sound of each such chord, and most importantly - for the same reason, in many cases it is easier to play, without losing the main sound and harmony of the work.
How the appeal of any chord is formed
Minimum chord can consist of three steps formed by different intervals. Suppose we are dealing with a standard major chord, built from the "to" note, which includes large and small third. Thus, in order to make his first appeal, we transfer the lowest note, that is, “do,” to an octave higher. It turns out that now our chord begins with the sound "mi" and consists already of a small third and a pure quart. The triad appeals will be complete if we consider the third of them. In this case, the note “mi” is already carried an octave higher, and the chord is built with “salt”. Its structure will now be as follows: a pure quart and a large third. The names of these calls are simple and come from the intervals from which they begin. The main chord is tonic, its first appeal is the tertzkvartakkord, and the second is the quarter tart.
Why triad and its appeals are considered the basis of any melody
As already mentioned, each triad is the main chord in any fret. In major or minor, in Dorian fret or Lydian - this chord is built on three levels of the scale. Thus, the tonic (as this consonance is called) begins with the first step of the fret, then affects the third and fifth. The first note is considered the most stable, all the rest are auxiliary. Consequently, tonal triad reversals can be used for ease of busting in accompaniment, there will be no fundamental difference in sound. An exception can be considered those cases when the work ends in a particular chord. Terzkvart and quarterter in such cases will sound unstable, unlike tonic.
How other chords are modified
In the theory and practice of music, there are various types of triads, which may depend on a particular fret or be independent. This is a standard minor harmony, which is built on small and large third. Among the most common chords, increased and decreased are also found. They consist of either two large thirds or two small thirds, respectively. Only in this case, the triads will be much more interesting. In an enlarged chord, when moving the lower note an octave higher, we get a reduced quart. In sound, it is identical to the big third, the only difference is in writing. Therefore, each appeal of the increased chord is no different from its source. In a reduced note, the lower note, carried up, will form an enlarged quart or triton. The sound is sharp and specific, especially in combination with a small third.
Other Chord Reference Items
Surely you noticed that it was pointed out that a triad could contain not only small intervals, such as thirds and quarts, but also very large ones - sextes. How exactly do they fit into such consonances and how does this affect perception? In fact, each appeal of the main triads of the fret contains this interval, namely, it is formed by extreme sounds. For example, the first variation of the tonic triad is also a sixth chord, since depending on the major or minor fret its extreme notes can be the basis for a minor or major sext. The second appeal is a quartosextaccord. In major, its extreme sounds already form a large sixth, and in minor - small.
Why you need to change the structure of the chord
Many aspiring musicians do not always understand why it is necessary to reverse the main triads, if, in fact, the essence of the sound does not change from such metamorphoses. The answer to this question is easiest to get in the process of improvisation or composition. Sometimes even the same harmony, without deviations and auxiliary musical signs, in one of its addresses sounds completely different. For example, sextacord can often be heard in the design or in the middle of a piece. It is not as solid as tonic, but at the same time gives stability to the melody. Quartextextaccord is considered introductory, that is, after it, you definitely need to play a tonic triad.
Conclusion
Similarly to tonic chords in each scale, the adjacent subdominants and dominants are modified. Often this technique is used when you want to play the spread out accompaniment in the form of arpeggios or a simple enumeration of notes. This gives each piece more charm and ambiguity, but at the same time leaves the opportunity to preserve the unity of harmony.
