Diminished triad

For example, the diminished triad built on B, written as Bo, has pitches B-D-F: The chord can be represented by the integer notation {0, 3, 6}.

[7] If the music is in a minor key, diminished triads can also be found on the raised seventh note, ♯viio.

[6] This differs from the fully diminished seventh chord, which commonly occurs in root position.

[8] Walter Everett writes that "In rock and pop music, the diminished triad nearly always appears on the second scale degree, forming a generally maudlin and dejected iio with its members, 2–4–♭6.

"[9] Songs that feature iio include Santo & Johnny's "Sleep Walk", Jay and the Americans' "Cara Mia", and the Hollies' "The Air That I Breathe".

[9] Not so rare but rare enough so as to imply knowledge of and conscious avoidance on the part of rock musicians, examples of its use include Oasis' "Don't Look Back in Anger", David Bowie's "Space Oddity", and two in Daryl Hall's "Everytime You Go Away".
