Common chords are frequently used in modulations, in a type of modulation known as common chord modulation or diatonic pivot chord modulation. It moves from the original key to the destination key (usually a closely related key) by way of a chord both keys share. For example, G major and D major have 4 chords in common: G, Bm, D, Em.
The key is also appropriate for guitar music, with drop D tuning making two D's available as open strings. For some beginning wind instrument students, however, D major is not a very suitable key, since it transposes to E major on B ♭ wind instruments, and beginning methods generally tend to avoid keys with more than three sharps.
In the key of C major, these would be: D minor, E minor, F major, G major, A minor, and C minor. Despite being three sharps or flats away from the original key in the circle of fifths, parallel keys are also considered as closely related keys as the tonal center is the same, and this makes this key have an affinity with the original key.
Common-chord modulation (also known as diatonic-pivot-chord modulation) moves from the original key to the destination key (usually a closely related key) by way of a chord both keys share: "Most modulations are made smoother by using one or more chords that are common to both keys." [7] For example, G major and D major have four triad chords ...
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.
The 'major' alteration is usually superfluous, as a key description missing an alteration is invariably assumed to be major. In the German notation scheme, a hyphen is added between the pitch and the alteration (D-Dur). In German, Dutch, and Lithuanian, the minor key signatures are written with a lower case letter (d-Moll, d klein, d kleine terts).
Added tone chord notation is useful with seventh chords to indicate partial extended chords, for example, C 7add 13, which indicates that the 13th is added to the 7th, but without the 9th and 11th. The use of 2, 4, and 6 rather than 9, 11, and 13 indicates that the chord does not include a seventh unless explicitly specified.
A common chord progression with these chords is I-♭ VII–IV-I, which also can be played as I-I-♭ VII–IV or ♭ VII–IV-I-I. The minor-third step from a minor key up to the relative major encouraged ascending scale progressions, particularly based on an ascending pentatonic scale. Typical of the type is the sequence i–III–IV (or iv ...
