Abstract

This article represents a translated and revised version of the paper “Towards a Music Algebra: Fundamental Harmonic Substitutions in Jazz”. In this paper, the most common harmonic substitutions, at least as far as jazz music is concerned, is unconventionally addressed. The novelty consists of introducing a new method finalized to formally defining and logically applying all the fundamental harmonic substitutions, by exploiting an unusually rigorous notation. After defining the substitutions and discussing their applicability, we resort to them in order to modify some simple harmonic progressions substantially based upon a banal major turnaround. As explicitly suggested by the title, the modifications are carried out by following an extremely formal line of reasoning: all the logic passages are accurately described by resorting to a notation so similar to the one commonly employed in mathematics and physics, that the harmonic analysis of a song turns out to be de facto comparable to the demonstration of a theorem. Nel presente articolo vengono discusse, in modo non convenzionale, le sostituzioni armoniche più diffuse, almeno per quanto inerente alla musica Jazz. La novità consiste nella presentazione di un metodo abbastanza innovativo, finalizzato alla definizione formale nonchè all’applicazione logica delle sostituzioni di cui sopra, ricorrendo ad una notazione inusualmente rigorosa. Dopo aver definito le sostituzioni, altresì dioscutendone l’applicabilità, si ricorre ad esse onde modificare alcune semplici progressioni armoniche costruite, fondamentalmente, su un banale turnaround maggiore. Come esplicitamente suggerito dal titolo, le modificazioni sono effettuate seguendo una linea di ragionamento estremamente formale: i passaggi logici sono accuratamente descritti nella loro interezza, ricorrendo ad una notazione tanto simile a quella comunemente impiegata in campi come quelli della matematica e della fisica, che l’analisi armonica di un brano risulta paragonabile, di fatto, alla dimostrazione di un teorema.
