In music, a closely related key (or close key) is one sharing many common tones with an original key, as opposed to a distantly related key (or distant key). In music harmony , there are six of them: four of them share all the pitches except one with a key with which it is being compared, one of them shares all the pitches, and one shares the ...

When used with chord symbols, the Roman numerals represent the root of a triad built on the associated scale step. In music theory based on the practices of the common practice period and its derivations the chord numerals are often written in upper case for chords in the major family, and in lower case for chords in the minor family, with the usual "m" or "—" minor chord quality suffix ...
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. So if the song was in G minor, the key would be listed as B ♭ major, and G minor chords would appear as 6-.
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).
In contrast, in the chord-scale system, a different scale is used for each chord in the progression (for example mixolydian scales on A, E, and D for chords A 7, E 7, and D 7, respectively). [5] Improvisation approaches may be mixed, such as using "the blues approach" for a section of a progression and using the chord-scale system for the rest. [6]
Pressing a key on the keyboard makes the instrument produce sounds—either by mechanically striking a string or tine (acoustic and electric piano, clavichord), plucking a string (harpsichord), causing air to flow through a pipe organ, striking a bell , or activating an electronic circuit (synthesizer, digital piano, electronic keyboard).
Aeolian harmony [10] is harmony or chord progression created from chords of the Aeolian mode. Commonly known as the "natural minor" scale, it allows for the construction of the following triads (three note chords built from major or minor thirds), in popular music symbols: i, ♭ III, iv, v, ♭ VI, and ♭ VII.
