Universal key fractions (e.g. an A natural in the scale above becomes ) or, more commonly in written text, by inserting an accidental before the number (e.g. the same note becomes 5 or 4). In music theory aimed towards jazz and popular music, all triads are 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): When representing the triads rooted in a minor key, accidentals are used to indicate the chromatic alteration from the assumed major key roots indicated by numerals that don't have accidentals:

For example recent French scores or books may use the English system (this is especially common for chord symbols), but French users would read out that notation according to the Fixed Do system. Similarly a Dutch musician may refer to a written F orally as Fis. This article is concerned with written usage. To form a key designation, locate the note name in the pitch translation table and add the major/minor qualifier from the lower table as needed. Note that the 'major' alteration is usually superfluous, as a key description missing an alteration
