Chords

Triads In Root Position

            In harmony, notes are deployed vertically. The most basic propotions are between these vertically deployed notes which are triads. These basic chords can be in four different harmonious forms which are major, minor, diminished and augmented. The ranges which is constitue triads are thirds and fifths. Ex.11 is showed  triad names and which triad has which propotion.

                                                                                                                                             Ex.11

           

            In a scale, triads of degrees have different kinds. They are showed  as roman numerals. Major triads shown as capital letter, minor triads which are showed  as small letter roman numerals. Ex..12 Shows all triads of degrees in all kind of scales with symbols.

           

                                                                                                                                           

                                                                                                                             Ex.12                                                                                                           

            Sometimes, thirds of triads can be stand with an accidental signatures that except from scales key signatures. They are symbolize such as ( b ) and (#).

                                                                                                                                       Ex.13

Triads In All Inversions

            A note is a sound. There is no matter which sound in which pitch. However, for the propotion of triads, the intervals between the notes of triads can not  far away over an octave. Id est, a note can be stayed at an octav above or below.  In this case, triads takes a small addition to their symbols as distance between bottom note. If the root uppered  an octave, third is become a bottom note. Distance between the bottom note is become a sixth. The fifth note and the uppered root note become a third and a sixth.

Seventh Chords In Root Position

            The seventh chords are vertically formed from four different notes of a scale. There are five kinds of seventh chords such as major seventh, major minor seventh, minor seventh, half-diminished seventh and dimnished seventh. The symbols of the chords are M7, Mm7, m7, Ø and 7°.

The propotion of the chords is shown in Ex.13.

                                                                                                                                 Ex.15

Seventh Chords In All Inversions

            The seventh chords can be inverted like triads.  However, their symbols are different from of triads because of intervals. The seventh chords have four condition and four symbols.

                                                                                                                                  Ex.16

            If the note, symbolized by the number which is taken an accidental, the number takes the same accidental on leftside.
