Each note or degree of a scale has a technical name, this tell you where a particular note is in a scale and what it does. The note the scale begins on is called the Tonic, the fifth note of the scale is called the Dominant. This is the same for triads. The tonic triad is formed from the first, third and fifth note of a scale and has 3 positions (root position, 1st inversion and 2nd inversion)
The diagram below shows the names of triads in the scale of C Major with their technical name and Roman Numerals.
The diagram below shows the inversions along with their technical names in the scale of C Major. If the third of the chord is in the bass the Triad is init's first inversion, if the fifth of the chord is in thebass then it is in second inversion. If the seventh of the chord is in the bass then the triad is in it's third inversion.
The Different Types Of Triad
Triads on chords I, IV and V are Primary and those on II, III, VI and VII are Secondary. The three Primart triads are all that are necessary to harmonise each degree of the scale. The Secondart tiads are used to add variety and colour.
In a Major key all of the Primary Triads are Major and all of the Secondary Triads are Minor except for chord VII which is diminished. Inversion are used to give colour and make the transitions of the basssmoother. |
