Teoria armonia funcional 1 nestor crespo12/29/2022 ![]() ![]() We will practice with 44 progressions in the major mode and 40 in the minor mode using concepts of functional harmony: diatonic chords, secondary dominants, substitutes and modal interchange chords. The different strings sets are organized starting from the study of the fingerings of each type of triad, previously mentioned, in position and across the guitar neck. We will use four types of open triads: Major - Minor - Diminished and Augmented, both in fundamental position and in first and second inversion in string sets: 6 4 2 / 5 3 2 / 5 3 1 / 4 2 1 Practicing the different exercises, progressions and works, we will achieve a conscious and dynamic handling of the different fingerings and sonorities produced. The open triads are obtained by ascending or descending an octave the internal voice of a triad in closed position, either in root position or inverted, thus achieving a tenth interval between the bass and the upper voice. It is worth underlining how the description of CAT herein provided is to be considered as being merely qualitative, since the formal definition of the transformations would require the usage of an extremely rigorous notation, elsewhere exploited in order to introduce the so-called Music Algebra.The Spread triads is often used as a tool when we perform a musical arrangement, however, many instrumentalists and composers use the triads openly, thus achieving a greater expressive weight. The above-mentioned transformations, nothing but particularized inverse chord substitutions, arise from the analisis of a considerable number of traditional jazz compositions, carried out by accurately examining the so-called LEGO Bricks. The method is primarily based upon the application, carried out by following a specific order, of a set of transformations, named CAT (Cataldo advanced Transformations), by means of which any harmonic progression may be converted into a mere sequence of plagal and perfect cadences. In this article we briefly introduce an original method, the purpose of which fundamentally lies in providing musicians with a reliable instrument that may effectively assist them in carrying out the chord progressions analisys. ![]()
