Starting from the symmetrical chords, otonal chords flatten one note, while utonal chords sharpen one note. The 5-limit otonality is simply a just major chord, and the 5-limit utonality is a just minor chord. Thus otonality and utonality can be viewed as extensions of major and minor tonality respectively.
[7] For example, G major and D major have four triad chords in common: G major, B minor, D major and E minor. This can be easily determined by a chart similar to the one below, which compares triad qualities. The I chord in G major—a G major chord—is also the IV chord in D major, so I in G major and IV in D major are aligned on the chart.
Tonality is the arrangement of pitches and / or chords of a musical work in a hierarchy of perceived relations, stabilities, attractions, and directionality.. In this hierarchy, the single pitch or the root of a triad with the greatest stability in a melody or in its harmony is called the tonic.

The concept of harmonic function originates in theories about just intonation.It was realized that three perfect major triads, distant from each other by a perfect fifth, produced the seven degrees of the major scale in one of the possible forms of just intonation: for instance, the triads F–A–C, C–E–G and G–B–D (subdominant, tonic, and dominant respectively) produce the seven ...
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. In a minor scale, the third degree is a minor third above the tonic. Similarly, in a major triad or major seventh chord, the ...
Methods that establish the key for a particular piece can be complicated to explain and vary over music history. [citation needed] However, the chords most often used in a piece in a particular key are those that contain the notes in the corresponding scale, and conventional progressions of these chords, particularly cadences, orient the listener around the tonic.
From the major key's I–ii–iii–IV–V–vi–vii o progression, the "secondary" (minor) triads ii–iii–vi appear in the relative minor key's corresponding chord progression as i–iv–v (or i–iv–V or i–iv–V7): For example, from C's vi–ii–iii progression Am–Dm–Em, the chord Em is often played as E or E7 in a minor chord ...
