When there are many additional degrees, forward slashes are used instead of parentheses. The representation order follows the logic of showing the seventh first (if any) and then the additional degree in parentheses. Generally, we use parentheses when the chord has more than 4 degrees. Note: when the altered note is the fifth, the chord can also receive only the “+”, for example: C+.Īnother important detail to consider is the use of the parentheses. Augmented chords: can receive the symbol “#” or “+” next to the altered degree in question.We will explain the reason for this fourth when we go into the subject “tension notes”. These chords are usually accompanied by a perfect fourth. Suspended chords: are the chords that don’t have the third.In the case of the perfect fourth, we can also just say “fourth” and write “4”, without any additional symbols. The nomenclature of both does not use the symbol “M” or “maj” to represent the major degree, just C9 or C6 is used, for example. Note: when we say “ninth”, understand it as “major ninth”. However, in practice, not everyone makes this distinction, so caution is needed. To make it clear, it would be like saying: “ This chord has an added ninth, that is, it is the ninth added to a triad. When there is no minor seventh in the chord, it is made clear by the “add” symbol, as we have already seen. This is due to the fact that chords with ninth usually have the seventh too, so it is understood that the symbol “9” already informs that there is a seventh with it. Ninth chords with the minor seventh: they can only receive the number 9, or the number 7 followed by the number 9.When the chord also has the seventh, the American notation usually places only the number 9. These are the chords formed by a triad plus a ninth. Added ninth chords: receive the number 9 followed by the word add.On popular chord notation websites, people use the 7+ notation a lot, like this: C7+, but this is not the most suitable notation, since it is used for augmented chords. Examples: Cmaj7, CM7, Amaj7, AM7, Bm(7M), etc. Chords with the major seventh: they receive the number 7 followed by the word “maj” or the letter M.Chords with the minor seventh: they only receive the number 7.Overview about chords notation and symbolsĬontinuing our learning about chords and chord notations, we will see below the most widely used nomenclatures in chord dictionaries and song books.
