If so, instead of relying on the etymology, you can use the following mnemonic to help you: A cord is a single piece of string, while a chord is a group of notes – so the word that contains more letters is for the collection of notes. It is as simple as we can do it and please be pleased that we have not introduced the issue in core. The seven chords are Tertian chords constructed by adding a fourth note to a triad at the interval of a terz above the chord`s quinte. This creates the interval of one seventh above the chord root, the natural next step in the composition of tertic chords. The seventh chord, built on the fifth stage of the scale (the dominant seventh), is the only dominant seventh chord available in the major scale: it contains the three tones of the triad diminished by the seventh and is often used as a stronger substitute. A chord is a set of musical notes that are played or sung together to create a pleasant sound. A cord is a long flexible cord or rope that often consists of thinner, intertwined pieces. A chord, on the other hand, is “three or more musical tones that will be played together.” In some conventions (as in this article and related articles), large Roman numbers refer to major triads (for example. B I, IV, V), while roman numerals in small print denote soft triads (for example.
B I for a major chord and (i) for a minor chord or the use of the major key, ii, iii and vi, which constitute typical diatonic diurnal triads); other authors (e.g.B. Schönberg) use Roman capital letters for both the hard and small triads. Some authors use Roman capital letters to indicate that the chord in the major scale is diatonic, and lowercase Roman numerals to indicate that the chord in the minor scale is diatonic. . . .
