After this, there is a reconstruction, transcription and revision with the aim of achieving a critical edition of the original.
     The choice of the repertoire in concentrated exclusively on unpublished works or works that have been rarely performed in modern times.
     The instrumentation of  Cappella Teatina is based on the use of original instruments or faithful copies, with the pitch of the instruments of the time.

      Every composition is always prepared and considered in the context of the time in which it was conceived: the study and the reconstruction of the liturgy of the period, the historical and cultural background which helped form the original piece with reference to the figurative art of the period.
     It is these elements which the ensemble considers indispensable to a faithful and true reproduction.
     The intention of all of this is to penetrate into the depths and "pathos" of every composition, rediscovering the pleasure of "making music" and "creating culture" in an age which is loosing more and more its suggestion and fascination.

     Starting from the renaissance and up to and beyond the 17th century, the establishment of cappelle musicali (religious choirs and orchestras) were documented in Bologna, as in the principal european cities, which were linked to the cathedrals and to the main basilicas of every city. 

These institutions regularly carried out the accompaniment during the religious services and for many years were the principal means of diffusing music. Ss. Bartolomeo and Gaetano's basilica, built in the 17th century and directed by "chierici regolari di S. Gaetano" (also known as "Teatini fathers"), used the services of a Cappella Musicale up to 1796, the year in which Napoleon Bonaparte abolished all the religious orders and the institutions related to them.

     Today, at a distance of two hundred years, the Cappella Teatina ideally takes the heritage left by the ancient cappelle musicali so that the musical repertoire (Italian and foreign), created by great musicians and craftsmen is retrieved.
     The reproposal of this rich musical heritage is interpreted as trait d'union between our culture and the suggestive art that has to be kept alive and intense.
