What is the substitution of chords?
Most of all music compositions can be structurally defined as progression of harmonic chords. Chord is a combined sound of two or more music notes. Several centuries of music theorists have developed a good understanding of why and how chords change from one to the other. The composition is the substitution of chords of music technology, does not play another chord, and instead plays another that still adheres to the principles of harmony. In some respects, good substitution is always derived from the original chord to be played. It's called a tonic chord. In the key C Major, the tonic chord consists of three remarks C, E and G. Although it is a generalization, the path of music is from this tonic chord to its dominant chord based on the fifth tone. In the key C is dominant chordg, b and d.
by achieving the musical climax of the dominant chord, music returns to the Tonic chord. A creative, round harmonic step that music belowNiká to move from her tonic chord to his dominant and to a lesser extent back to the tonic is the progression of the chord. The traditional record of music theorists who express these chords are Roman numerals - I for the root, in the dominant and everything between VII. A 12-bar blues song could be rewritten: i-i-i-i / IV-IV-i-i / v-v-i-i.
any of these chords can be replaced by another. If you do so while maintaining a harmonious connection between previous and subsequent chords, the basic structure of the song remains. In the example of Blues, replacing the chord in the first tonic rods with its harmonious sub-dominant chord based on the fourth tone of the key-i-IV-IV-NEBHEMAGE Mark the song, but give it a more complex sound.
categorically, chord substitution falls into several different types. Another note can be added. For example, adding the seventh tone-C, E, G and B for i7 or C-Major-Seventh Actore-gives the original chord tense, anticipating sound. Notes can also be deducted from the original. NoJimicoded chord substitution may be a default change in tonic chord.
Substitution of chords is practiced by amateur and proficient musicians. Students of beginners can be provided well -known music whose original score of chords has been replaced by simpler ones that are more suitable for the student's skill level. At a high level of instrumental skills, however, say that an improvisational jazz pianist is an extremely difficult substitution technique.
The basic principle of this technique is the harmonious mapping of every note in the new chord in the ezaplated procedure. One of the more common substitutions called secondary dominant is to handle any given chord, as if it were a tonic and then instead of playing its equivalent harmonious dominant. Another substitution is to play the chord in your relative smaller key, usually adding the sixth tone of the key. I-A-Akord in C-Major can be played instead of C-E-G-A for the melancholic sound vi 7 or A-MINOR-SEVENTH.
There are other more difficult options for chord substitution. The new chord, usually slightly disapproving with the ear, can be inserted as a transitional step or a bridge between two perfectly good harmonious chords. Similarly, Discord can be introduced by adding the second tone to the chord. Its difficult use comes from the need to solve a dissonant sound with another chord in progression, a popular "chord". Very qualified musicians, such as improvisation jazz saxophonist John Coltrane, can subtitute, not just one chord, but several subsequent chords.
