Theoretical framework 11 1.1 The intervals that create more harmonic tension are those of M3 and 11 tritone 13 1.2 The notes that form the M3 intervals (CE/EC) and/or tritone (EB¬/A{E) locally resolve to the notes F or B, or to the chords that have these fundamentals. 15 1.3 The fifth of the fundamental is the less important note as regards the chord's harmonic function. 16 1.4 The 7M3 structure produces a tonal vector. 18 1.5 The htonal and Phrygian resolutions of M3 and tritone account for most cadences, secondary dominants and cadential harmonic progressions. 1.6 A fundamental and its main harmonics also have a 7M3 structure. 22 1.7 Most chords may be separated into one or two chords having the harmonic CEGB¬ complete or partial structure. 24 1.7.1 We may summarise the harmonic tension of most chords with one or two fundamentals, which results in eight large families of chords. 25 1.7.2 We can apply the fundamental symbology of chords to create or find local relaxed progressions of chords. 1.8 The reduction of tonal functions to three (tonic, subdominant and 25 dominant) may be explained by means of the tensions of M3 and tritone intervals. 2.

Why do we also notice relaxion* when we hear the so-called Phrygian cadence? Why does a specific succession of notes establish a (or several) tonic, and hearing this tonic (or tonic chord) produces a relaxation irrespective of the previous chord? Which tension do the chords of the Neapolitan sixth and those of the augmented sixth establish? Why is a specific succession of chords fluent and released and another produces tension? In the following pages we will try to provide answers to these and other questions, always trying to look for the reasons accounting for musical tensions and relaxions . Furthermore, we will inquire into the nature of sound and our harmonic perception. We are aware of the fact that many of these questions could be answered in official theory by taking as a basis a scale and its associated concepts: degrees, tonal functions, cadences, etc.; nevertheless, there is usually no acoustic-harmonic explanation provided for the tensions and relaxions that are produced. In my book La convergència harmònica (Balsach, 1994) and in the article “Applications of virtual pitch theory in music analysis” (Balsach, 1997), I already introduced many of the concepts and explanations that appear in the following pages. However, this time I have tried to present the main ideas in a more ordered and structured way, besides including new contributions and suggestions, mainly in the field of tonality. This is the reason why the first chapter has been devoted to presenting in an abridged and ordered form the main and new ideas and conclusions of the book . In fact, if anyone wanted to get an idea of the book’s contents, they could achieve it by just reading the first chapter. I proceed on the basis —and this is not new— that the continuous perception of the harmonics phenomenon of a sound —from birth— is what shapes in the brain the sensations of harmonic tensions and relaxions when we listen to music. And, according to our theory, we will see that only the first seven harmonics play a role in it —at the most—, being the third, the interval of fifth (12th), the main responsible for harmonic and tonal tensions. Nevertheless, curiously enough, this is in contrast 8 Los fundamentos de las tensiones armónicas with the fact that, apart from the octave, the fifth of a fundamental is the least important note in a chord; and this is so precisely because it does not produce tension in it, as it happens with the octave (the second harmonic), which does not produce tension in it either. Conversely, the intervals that are closer to the fifth (a difference of a semitone) produce tension, such as the tritone intervals (augmented fourth/diminished fifth) and the minor sixth/major third ones. As we will see, this is a fundamental point in the theory, for the situation of these intervals in the chords will provide us with much information on the resolutive “preferences” of the chord to free this tension of the “quasi -fifth “ interval that the auditory system perceives as “something is wrong here” in the chord (as a kind of “dissonance”). We will see that the tension of these “quasi-fifth” intervals and the tendency of the notes to their lower fifth are also responsible for the tonality (we will see that a major third and a tritone combined in a specific way create the most powerful tonal vector that may appear in a score). The formations of the major and minor scales with leading-tone will be the result of such tensions, but not the cause. That is to say, we do not base ourselves on the degrees of a scale to explain the harmonic or tonal discourse. Regarding tonal functions, we could say that our theory is a neo-Riemannian theory that also agrees with some aspects of Ernö Lendvai’s tonal axes theory. Over the years, I have reached the conclusion that we may separately study three kinds of harmonic tensions: the purely local tensions or relaxions between two chords or arpeggios, irrespective of the tonal memory, which I call homotonic relaxions, the tonal tensions, and the chord tensions taking into account their dissonance or consonance (which I call sonance tensions). To these three harmonic tensions we should add the melodic tensions that, despite being intertwined with the harmonic tensions, have their own laws, among which the second’s descending movements producing relaxion, stand out. The second chapter analyses thoroughly the phenomenon of the harmonics and the virtual pitch (missing fundamental) theory.
