The Musica Ficta Musical Association was founded by a group of musicians in the city of Rimini. Its main purpose is to promote the musical culture both locally, in the Town of Rimini, with the organization of concerts, and internationally through some Workshops leaded by well-known artists, a Choral Competition and an Organ Competition and, finally, by the activity of a fine Vocal Ensemble. One complication of the term musica ficta is that it carries two distinct although not unrelated meanings, one arising from medieval and Renaissance hexachord theory and the other from modern dilemmas of editorial and performance practice. In the medieval sense, musica ficta involves inflections extra manum or "outside the hand" - the Guidonian hand defining the standard hexachords and steps of the gamut. In contrast, musica recta involves hexachords and steps within this gamut - or a transposed version of it. In the colloquial modern sense, however, musica ficta can often mean "unwritten accidentals" supplied in performance.
