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:
Stopped note On plucked string instruments with frets, such as the guitar, the pitch of a stopped note is determined by the left hand pressing (stopping) the string at one of the frets. Stopped note On string instruments, a stopped note is a note whose pitch has been altered from the pitch of the open string by the player's left hand pressing (stopping) the string against the fingerboard. On bowed string instruments, a stopped note is a played note that is fingered with the left hand, i.e. not an open string. This assists with tone production, the addition of vibrato, and sometimes
