The chord-scale system is a method of matching, from a list of possible chords, a list of possible scales. [2] The system has been widely used since the 1970s. [3] However, the majority of older players used the chord tone/chord arpeggio method. The system is an example of the difference between the treatment of dissonance in jazz and classical ...
The key note, or tonic, of a piece of music is called note number one, the first step of (here), the ascending scale iii–IV–V. Chords built on several scale degrees are numbered likewise. Thus the chord progression E minor–F–G can be described as three–four–five, (or iii–IV–V). A chord may be built upon any note of a musical scale.
Minor chords are noted with a dash after the number or a lowercase m; in the key of D, 1 is D major, and 4- or 4m would be G minor. Often in the NNS, songs in minor keys will be written in the 6- of the relative major key. if the song was in G minor, the key would be listed as B ♭ major, and G minor chords would appear as 6-.
Though the scale is not a chord, and might never be heard more than one note at a time, still the absence, presence, and placement of certain key intervals plays a large part in the sound of the scale, the natural movement of melody within the scale, and the selection of chords taken naturally from the scale.

Jazz chords are chords, chord voicings and chord symbols that jazz musicians commonly use in composition, improvisation, and harmony. In jazz chords and theory, most triads that appear in lead sheets or fake books can have sevenths added to them, using the performer's discretion and ear. [1] For example, if a tune is in the key of C, if there ...
For instance, in C major, a jazz musician may alter the V chord, G 7 (G–B–D–F), with a flattened fifth, producing the chord G 7 ♭ 5 (G–B–D ♭ –F). An improviser might then choose a scale containing these four notes, such as the G whole tone scale, the G octatonic scale, or a mode of either D or A ♭ melodic minor
Common chord in the keys of G, D, and A major; as well as E, B, and F ♯ minor. A common chord, in the theory of harmony, is a chord that is diatonic to more than one key or, in other words, is common to (shared by) two keys. [1] A "common chord" may also be defined simply as a triadic chord [2] (e.g., C–E–G), as one of the most commonly ...
In music theory, Roman numeral analysis is a type of harmonic analysis in which chords are represented by Roman numerals, which encode the chord's degree and harmonic function within a given musical key. Specific notation conventions vary: some theorists use uppercase numerals (e.g. I, IV, V) to represent major chords, and lowercase numerals (e ...
