Chord Formation

Chord Formation

As years in the 17th Century passed, a new texture of musical writing became increasingly important in the musical world, a change to the ultimate emergence of opera, oratorio, the symphony, concerto, and associated patterns. The shift was from two lines of music which made polyphonic harmony, to a new style in which one melody line was to be played over a group of held notes, a group of tones called a chord. This new texture is called homophonic. In usual practice a chord is three notes, or a triad, in which the key of the piece becomes the root note of the chord. Then depending on the nature of the chord, intervals are extended from the root to other notes in the scale( having 7 notes to chose from). [AW] {MI}
