Na minha concep\u00e7\u00e3o, anteriormente explicada (<a href=\"https:\/\/www.blogs.unicamp.br\/musicologia\/2019\/04\/17\/16\/\" target=\"_blank\" rel=\"noopener noreferrer\">aqui<\/a> e <a href=\"https:\/\/www.blogs.unicamp.br\/musicologia\/2019\/04\/24\/17\/\" target=\"_blank\" rel=\"noopener noreferrer\">aqui<\/a>), as escalas e tr\u00edades maior e menor podem ser todas derivadas unicamente da s\u00e9ria harm\u00f4nica real, (a s\u00e9rie dos overtones, conforme \u00e9 chamada, no livro de Levy). Para isso, basta considerar simultaneamente 2 s\u00e9ries harm\u00f4nicas reais (de overtones); a s\u00e9rie principal, do centro tonal em quest\u00e3o (no exemplo, D\u00f3), a s\u00e9rie da sua dominante (representada pelo seu segundo harm\u00f4nico; no exemplo, Sol) e a s\u00e9rie cujo centro tonal em quest\u00e3o \u00e9 a sua dominante, ou seja, a sua subdominante (dada pela s\u00e9rie da qual o centro tonal equivale ao seu segundo harm\u00f4nico; no exemplo, F\u00e1).<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter size-large wp-image-1143\" src=\"https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/3_harmonic_series-929x1024.png\" alt=\"\" width=\"700\" height=\"772\" srcset=\"https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/3_harmonic_series-929x1024.png 929w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/3_harmonic_series-272x300.png 272w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/3_harmonic_series-768x847.png 768w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/3_harmonic_series-1393x1536.png 1393w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/3_harmonic_series-1857x2048.png 1857w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/3_harmonic_series-635x700.png 635w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<p>As duas tr\u00edades menores, formadas pelas notas das tr\u00edades principal, subdominante e dominante, permitem formar os modos menores das escala diat\u00f4nica, como o d\u00f3rico (segundo grau) e o e\u00f3lio (sexto grau).<\/p>\n<blockquote><p>Exemplos musical do modo d\u00f3rico (grau II)<\/p><\/blockquote>\n<audio class=\"wp-audio-shortcode\" id=\"audio-1140-1\" preload=\"none\" style=\"width: 100%;\" controls=\"controls\"><source type=\"audio\/mpeg\" src=\"https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/dorico.mp3?_=1\" \/><a href=\"https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/dorico.mp3\">https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/dorico.mp3<\/a><\/audio>\n<blockquote><p>Exemplos musical do modo e\u00f3lio (grau VI)<\/p><\/blockquote>\n<audio class=\"wp-audio-shortcode\" id=\"audio-1140-2\" preload=\"none\" style=\"width: 100%;\" controls=\"controls\"><source type=\"audio\/mpeg\" src=\"https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/eolio.mp3?_=2\" \/><a href=\"https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/eolio.mp3\">https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/eolio.mp3<\/a><\/audio>\n<p>Conforme visto <a href=\"https:\/\/www.blogs.unicamp.br\/musicologia\/2019\/06\/05\/22\/\" target=\"_blank\" rel=\"noopener noreferrer\">anteriormente<\/a>, as tr\u00edades s\u00e3o formadas por 2 intervalos sucessivos de ter\u00e7a: simbolizados por \u201cM\u201d, para ter\u00e7a maior (formada pelo intervalo de 4 semitons) e \u201cm\u201d, para ter\u00e7a menor (formada pelo intervalo de 3 semitons). Como pode-se observar na figura anterior, na s\u00e9rie harm\u00f4nica real, os intervalos M e m s\u00e3o respectivamente o quarto e o quinto intervalo que ocorre entre a sequ\u00eancia natural de harm\u00f4nicos. Estes s\u00e3o antecedidos apenas pelos intervalos de oitava, quinta e quarta. Assim, os intervalos ocorrem numa sucess\u00e3o de conson\u00e2ncia para disson\u00e2ncia, iniciando pela oitava, que \u00e9 o intervalo mais consonante, na seguinte ordem (da esquerda para a direita, ou seja, do mais grave para o mais agudo): oitava, quinta, quarta, M (ter\u00e7a maior), m (ter\u00e7a menor). No caso da tr\u00edade maior, tem-se M, seguido e m. No caso da tr\u00edade menor, tem-se, m, seguido de M. Assim, o reverso (ou seja, a harmonia negativa) da tr\u00edade maior \u00e9 uma tr\u00edade menor, e o da tr\u00edade menor \u00e9 uma tr\u00edade maior. Eu disse <a href=\"https:\/\/www.blogs.unicamp.br\/musicologia\/2019\/05\/08\/19\/\" target=\"_blank\" rel=\"noopener noreferrer\">anteriormente<\/a> que existem tamb\u00e9m outras 2 tr\u00edades importantes, a aumentada, formada por dois M, e a diminuta, formada por dois m. Como ambas s\u00e3o sim\u00e9tricas (como um pal\u00edndromo) , o reverso da tr\u00edade diminuta \u00e9 tamb\u00e9m uma tr\u00edade diminuta, e o reverso de uma tr\u00edade aumentada, \u00e9 tamb\u00e9m uma tr\u00edade aumentada. Na tr\u00edades formadas pelas notas da escala diat\u00f4nica, tem-se apenas tr\u00edades maiores (I, IV, V) tr\u00edades menores (II, III, VI) e uma tr\u00edade diminuta (VII). N\u00e3o existe a ocorr\u00eancia natural de tr\u00edades aumentadas na escala diat\u00f4nica. Assim, na harmonia negativa, a tr\u00edade maior torna-se uma tr\u00edade menor; a tr\u00edade menor torna-se uma tr\u00edade maior, e a tr\u00edade diminuta continua sendo uma tr\u00edade diminuta.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-large wp-image-1144\" src=\"https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/graus-e-triades-1024x250.png\" alt=\"\" width=\"700\" height=\"171\" srcset=\"https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/graus-e-triades-1024x250.png 1024w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/graus-e-triades-300x73.png 300w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/graus-e-triades-768x188.png 768w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/graus-e-triades-1536x376.png 1536w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/graus-e-triades-700x171.png 700w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/graus-e-triades.png 1848w\" sizes=\"(max-width: 700px) 100vw, 700px\" \/><\/p>\n<p>Desse modo, tra\u00e7a-se uma divis\u00e3o imagin\u00e1ria entre o modo maior e o modo menor, a fim de espelhar a escala crom\u00e1tica, de acordo com a tonalidade.

Este processo fica mais evidente ao se dispor as 12 notas ao redor de um c\u00edrculo e representar o eixo de reflex\u00e3o entre harmonia positiva e negativa.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter wp-image-1145\" src=\"https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/bola-harmonia-negativa.png\" alt=\"\" width=\"444\" height=\"379\" srcset=\"https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/bola-harmonia-negativa.png 681w, https:\/\/www.blogs.unicamp.br\/musicologia\/wp-content\/uploads\/sites\/182\/2019\/12\/bola-harmonia-negativa-300x256.png 300w\" sizes=\"(max-width: 444px) 100vw, 444px\" \/><\/p>\n<p>Uma outra maneira de chegar ao mesmo resultado \u00e9 atrav\u00e9s da invers\u00e3o do modo J\u00f4nio (grau I) para o seu modo refletido (visto no <a href=\"https:\/\/www.blogs.unicamp.br\/musicologia\/2019\/12\/25\/42\/\" target=\"_blank\" rel=\"noopener noreferrer\">artigo anterior<\/a>) que equivale ao modo Fr\u00edgio (grau III).

Conforme disse no artigo anterior, as polaridades que determinam as notas da tr\u00edade maior (I, II e V), se mant\u00eam entre a passagem da harmonia positiva para a negativa. Assim, a estrutura continua com a mesma fun\u00e7\u00e3o tonal, o que permite explorar tanto varia\u00e7\u00f5es mel\u00f3dicas de um tema quanto varia\u00e7\u00f5es harm\u00f4nicas de sua cad\u00eancia, e estas n\u00e3o precisam necessariamente ser realizadas de modo completo, mas por exemplo, substituindo alguns acordes espec\u00edficos de uma sequ\u00eancia harm\u00f4nica, como foi o exemplo acima, com a dominante. O mesmo pode ser feito para a subdominante ou para outros graus e fun\u00e7\u00f5es. Apesar disso, nem todas as substitui\u00e7\u00f5es s\u00e3o esteticamente interessantes (e esta predile\u00e7\u00e3o obviamente muda de acordo com o indiv\u00edduo o o g\u00eanero musical). O positivo da harmonia negativa \u00e9 oferecer novas possibilidades de escolha de harmoniza\u00e7\u00f5es, tanto para o compositor quanto para o m\u00fasico interprete, que procura novas formas de interpretar uma pe\u00e7a conhecida. Apesar deste princ\u00edpio se basear numa estrutura que na verdade n\u00e3o existe (a s\u00e9rie dos undertones) ela funciona, afinal tem sua fundamenta\u00e7\u00e3o, por outro caminho, na s\u00e9rie harm\u00f4nica real. Al\u00e9m disso, a nossa cogni\u00e7\u00e3o foi desenvolvida pela evolu\u00e7\u00e3o para cumprir com grande precis\u00e3o a fun\u00e7\u00e3o de detectar padr\u00f5es. Quando uma pe\u00e7a \u00e9 baseada numa estrutura complexa, mesmo que n\u00e3o detectemos diretamente qual \u00e9 esta organiza\u00e7\u00e3o, muitas vezes como que a sentimos. Temos a impress\u00e3o quase que intuitiva de que por traz daquela informa\u00e7\u00e3o que nos \u00e9 apresentada, existe uma ordem que a rege. Por\u00e9m o que mais faz com que a harmonia negativa funcione \u00e9 o fato dela ser baseada na estrutura tonal, que por sua vez, baseia-se na s\u00e9ria harm\u00f4nica; o fen\u00f4meno ac\u00fastico que embasa e orienta toda a teoria musical, que vem se perpetuando e, pelo que parece, continuar\u00e1 ainda sendo a predile\u00e7\u00e3o da humanidade por muito tempo.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Refer\u00eancias:\u00a0<\/strong><\/p>\n<p>Ernst Levy. \u201cA Theory of Harmony\u201d.
