TRIADS AND OTHER THREE NOTE CHORDS
by PJVillanueva
Triads are three note chords: They are formed by a Root
(also Tonic), a 3rd (Major or minor)and a 5th (perfect,
diminished or augmented).
Any chord may sound slightly different according to the
position of the Root and yet have the same structure and
this is mostly true with triads.
When the Root is played at the bottom the triad is said
to be in Root position. When the Root is played in the
highest position after 3rd and 5th it is said to be the
1st inversion and when it's played in between 5th and 3rd
it is called 2nd inversion. Any of these forms may fit
better other preceding or following chords and sound more
musical because of the better connection of the relative
moving chord voicings.
But let's see first some Major triads and their inversions.
