Added tone chord
From Free net encyclopedia
An added tone chord is a triadic chord with an extra "added" note, such as the added sixth. This includes chords with an added thirteenth and farther "extensions", but that do not include the intervening thirds as in an extended chord.
An added sixth chord ends songs including Hank Williams' "Hey, Good Lookin'", Carl Perkins' "Movie Magg" and "Blue Suede Shoes", Ronnie Hawkins' "Red Hot", Chuck Berry's "Rock and Roll Music", and Scotty Moore's accompaniment in Elvis Presley's "That's All Right (Mama)".
An example of an added tone chord by Igor Stravinsky (Marquis 1964):

An added tone (G) chord with mixed thirds, a major third and minor third, by William Schuman (ibid):

In such cases the thirds are usually separated by an octave or more.
An added tone chord with a tone added a perfect fourth below the root may suggest polytonality.
Suspended chords
A suspended chord is a chord in which the third is replaced or accompanied by either a fourth or a major second, although the fourth is far more common.
This type of sound is borrowed from the contrapuntal technique of suspension, where a note from a previous chord is carried over to the next chord, and then resolved down to the third or tonic, suspending a note from the previous chord. However, in a suspended chord the added tone does not necessarily resolve.
Suspended chords are most commonly found in folk music and popular music.
Contrast with sixth chord.
