Beck's cognitive triad, also known as the negative triad, [1] [2] is a cognitive-therapeutic view of the three key elements of a person's belief system present in depression. It was proposed by Aaron Beck in 1967. [ 3 ]
A minor triad has a minor third (m3) on the bottom, a major third (M3) on top, and a perfect fifth (P5) between the outer notes. In harmonic analysis and on lead sheets, a C minor chord can be notated as Cm, C−, Cmin, or simply the lowercase "c". A minor triad is represented by the integer notation {0, 3, 7}.
A major triad has a major third (M3) on the bottom, a minor third (m3) on top, and a perfect fifth (P5) between the outer notes. In harmonic analysis and on lead sheets, a C major chord can be notated as C, CM, CΔ, or Cmaj. A major triad is represented by the integer notation {0, 4, 7}.
For example, the minor triad in root position is made up of the 10th, 12th and 15th harmonics, and 10 / 10 , 12 / 10 and 15 / 10 meets the definition of otonal. A better, narrower definition requires that the harmonic (or subharmonic) series members be adjacent. Thus 4:5:6 is an otonality, but 10:12:15 is not.
A cognitive distortion is a thought that causes a person to perceive reality inaccurately due to being exaggerated or irrational.Cognitive distortions are involved in the onset or perpetuation of psychopathological states, such as depression and anxiety.
A major triad consists of a major third followed by a minor third and is built on scale degrees 1, 3 and 5 (or 4, 6 and 1, for the subdominant, and 5, 7 and 2, for the dominant, the other two major triads that can be formed from the major scale). A minor triad consists of a minor third followed by a major third and is built on scale degrees 2 ...
Major and minor third in a major chord: major third 'M' on bottom, minor third 'm' on top. Major and minor may also refer to scales and chords that contain a major third or a minor third, respectively. A major scale is a scale in which the third scale degree (the mediant) is a major third above the tonic note.
Riemann's "dualist" system for relating triads was adapted from earlier 19th-century harmonic theorists. The term "dualism" refers to the emphasis on the inversional relationship between major and minor, with minor triads being considered "upside down" versions of major triads; this "harmonic dualism" (harmonic polarity) is what produces the change-in-direction described above.
