Bach: tuning and symbology
Graziano Interbartolo studied the acrostic found on the title-page of the First Book of Bach's Well-Tempered Clavier, proposing a new interpretation. It suggests a new kind of temperament, which is fully working and capable, at the same time, to impress into each key a well-defined character. It is, precisely, a "well"-tempered system, realizing a synthesis between the archaic early subdivisions of the octave and the manifold nuances of the Baroque era, as a prelude to the soul's affections which will constitute the creative stimuli for the following centuries.
Graziano Interbartolo obtained the Ministry's Diploma as a Master Restorer of Historical Organs at the Istituto Superiore per la Conservazione e il Restauro. He has worked on numerous occasions in cooperation with the Authorities for the Cultural Heritage in Genoa, Turin, Urbino, Avellino and Naples. He is an invited professor of organology and temperaments at the Conservatory G. Verdi of Turin. He wrote the technical section of the collective book "Bach 1722. Il Temperamento di Dio" (Finale Ligure: Edizioni Bolla, 2007). He is the author of technical-scientific papers about researches and experiences in the field of organ-making; he writes for the specialist journals L'Organo; Informazione organistica; and Organi liguri.
