For example, a C major triad uses the notes C–E–G. This spells a triad by skipping over D and F. While the interval from each note to the one above it is a third, the quality of those thirds varies depending on the quality of the triad: major triads contain a major third and perfect fifth interval, symbolized: R 3 5 (or 0–4–7 as ...
In harmonic analysis and on lead sheets, a C major chord can be notated as C, CM, CΔ, or Cmaj. A major triad is represented by the integer notation {0, 4, 7}. A major triad can also be described by its intervals: the interval between the bottom and middle notes is a major third, and the interval between the middle and top notes is a minor third.
The diatonic harmonization of any major scale results in three major triads, which are based on the first, fourth, and fifth scale degrees. The triads are referred to as the tonic chord (in Roman numeral analysis , symbolized by "I"), the subdominant chord (IV), and the dominant chord , (V), respectively. [ 3 ]
For instance, the notation C/E bass indicates a C major triad in first inversion i.e. a C major triad with an E in the bass. Likewise the notation C/G bass indicates that a C major chord with a G in the bass (second inversion). See figured bass for alternate method of notating specific notes in the bass.
For example, G major and D major have 4 chords in common: G, Bm, D, Em. This can be easily determined by a chart similar to the one below, which compares chord qualities. The I chord in G major—a G major chord—is also the IV chord in D major, so I in G major and IV in D major are aligned on the chart.
In some fake books and lead sheets, all triads may be represented by upper case numerals, followed by a symbol to indicate if it is not a major chord (e.g. "m" for minor or "ø" for half-diminished or "7" for a seventh chord). An upper case numeral that is not followed by a symbol is understood as a major chord.
In Baroque music, G major was regarded as the "key of benediction". [1] Of Domenico Scarlatti's 555 keyboard sonatas, G major is the home key for 69, or about 12.4%, sonatas. In the music of Johann Sebastian Bach, "G major is often a key of 6 8 chain rhythms", according to Alfred Einstein, [2] although Bach also used the key for some 4
This E ♭ major triad is what would be called the upper structure. Considered in relation to the root C, the notes of this E ♭ major triad function, respectively, as the sharpened ninth (the root of the E ♭ major chord), fifth, and seventh in relation to that root.
