Roman Numerals
Popular notation for chords and progressions
Roman numerals can be used to notate chords and chord progressions independent of a key. You have the option to display roman numerals instead of chord names in a Palette. The Pro edition of Synfire also supports writing chords and progressions as text input in this format.
