Musica ficta (from Latin, 'false', 'feigned', or 'contrived' music) was a term used in European music theory from the late 12th century to about 1600 to describe any pitches, whether notated or to be added by performers in accordance with their training, that lie outside the system of musica recta or musica vera ('correct' or 'true' music) as defined by the hexachord system of Guido of Arezzo (Bent and Silbiger 2001) — loosely synonymous with accidental.
In modern usage, the term is often loosely applied to all unnotated inflections (whether properly recta or ficta) that must be inferred from the musical context and added either by an editor or by the performers themselves (Bent and Silbiger 2001). However, words often used in reference books to define musica ficta, such as "chromatic", "inflection", "alteration", and "added accidentals" are not proper representations of the way ficta was defined by medieval and renaissance theorists (Bent 1984, 47).
Contrary to the modern concept of altering single notes, what musicians up to the 16th century did was to "operate musica ficta" on whole linear segments, which redefines the relationships between the letter-names in the scale. It is a matter of invoking a sub-system of ficta hexachords, not just individual notes, that fall outside of the musica recta system (Bent 1984, 20).
The crucial tool for medieval singers was the solmisation system, in which the total pitch space was represented by overlapping hexachords, shown mnemonically in the Guidonian hand, used to demonstrate where semitones occur amongst whole steps, by pointing to the joints of the fingers. The notes of the basic system of three hexachords is called musica recta or musica vera. This system encompasses the three most common semitone steps, B–C, E–F, and A–B♭, all solmised as "mi-fa". Change from one to another of these three basic hexachords was permitted, and the point of change was termed a "mutation". In the 14th century theorists extended this system to include semitones in other positions, indicated by the same mnemonics. This involved transposing hexachords to "alien pitches" or "unaccustomed places". These were classified as musica ficta, where the hexachord is specially created for the sake of the mi-fa semitone step (Bent 1972, 79–80). Renaissance Spanish Music Theorists, such as Domingo Marcos Durán, were sometimes explicit in the use of the hexachords of music ficta. In his Lux Bella of 1492 Durán gave a circular diagram with hexachords to indicate B♭, E♭, A♭, F♯, and C♯ (Durán 1492, 10).
One common (though not exclusive) use of ficta was to avoid harsh harmonic or melodic intervals such as the tritone, for example the use of a E♭ instead of a E♮ to avoid dissonance with a B♭ in another part.
In modern transcriptions of medieval and Renaissance music, ficta are usually indicated by an "accidental" sign appearing above the note. (In modern notation, accidentals are written before the note, not above.)
History of theory
Music theorists from Odo of Cluny in the 10th century to Zarlino in the 16th gave highly different rules and situations for the application of ficta. Thus the controversy is not only among contemporary musicologists; theorists of the Late Middle Ages were never in agreement on the rules of ficta either.
Contrapuntal treatises of the Renaissance, such as Johannes Tinctoris's Liber de arte contrapuncti (1477) and Gioseffo Zarlino's Le istituzioni harmonice (1588), described resolution at cadences through a major sixth into the octave or the inversion, a minor third closing to a unison, which, unless the other voice already descends by a semitone, necessitates the rising voice to add a sharp (see dyadic counterpoint) (Tinctoris 1961,[page needed]; Zarlino 1968, 144–45).
