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:
Minor scale lowered 7th degree found in the natural minor in order to avoid the augmented triad (III) that arises in the ascending form of the scale. In jazz, only the ascending form of the scale is usually used. Examples of the use of melodic minor in rock and popular music include Elton John's "Sorry Seems To Be The Hardest Word", which makes, "a nod to the common practice... by the use of F [the leading tone in G minor] as the penultimate note of the final cadence." In modern notation, the key signature for music in a minor key is typically
