These chords are all borrowed from the key of E minor. Similarly, in minor keys, chords from the parallel major may also be "borrowed". For example, in E minor, the diatonic chord built on the fourth scale degree is IVm, or A minor. However, in practice, many songs in E minor will use IV (A major), which is borrowed from the key of E major.

In tonal music, chord progressions have the function of either establishing or otherwise contradicting a tonality, the technical name for what is commonly understood as the "key" of a song or piece. Chord progressions, such as the extremely common chord progression I-V-vi-IV, are usually expressed by Roman numerals in
Dyads can be classified by the interval between the notes. [2] For example, the interval between C and E (four half steps) is a major third, which can imply a C major chord, made up of the notes C, E and G. [3] In a triadic context chords with omitted thirds may be considered "indeterminate" triads. [4]
Equal chords are subtended by equal angles from the center of the circle. A chord that passes through the center of a circle is called a diameter and is the longest chord of that specific circle. If the line extensions (secant lines) of chords AB and CD intersect at a point P, then their lengths satisfy AP·PB = CP·PD (power of a point theorem).
According to James Bennighof: "Replacing an expected final minor chord with a major chord in this way is a centuries-old technique—the raised third of the chord, in this case G ♯ rather than G natural, [verification needed] was first dubbed a 'Picardy third' (tierce de Picarde) in print by Jean-Jacques Rousseau in 1797 ... to express [the ...

In Roman numeral analysis, the supertonic chord is typically symbolized by the Roman numeral "ii" in a major key, indicating that the chord is a minor chord (in C: D–F–A). In a minor key, it is indicated by "ii o" if it is built on the a natural minor scale, indicating that the chord is a diminished chord (in C: D–F–A ♭).
