Ma come se la cavano con la musica? Il substack <a href=\"https:\/\/aug5th.substack.com\/\">Augmented Fifth<\/a> ha come tema &#8220;the intersection between classical music &amp; AI&#8221; e ha ideato <a href=\"https:\/\/aug5th.substack.com\/p\/the-bach-benchmark\">un benchmark<\/a>: fare scrivere a un LLM un corale nello stile di Bach. Per chi non \u00e8 un esperto musicale, questi corali (che poi sono quelli della tradizione luterana) hanno 16 battute divise in quattro gruppi di quattro, si cantano a quattro voci e hanno una struttura fissa, con una modulazione (un cambio di tonalit\u00e0) nel terzo gruppo per poi ritornare alla tonalit\u00e0 di partenza. <a href=\"https:\/\/x.com\/aug5thmusic\/status\/2096030719156089029\">Questo<\/a> \u00e8 il risultato ottenuto con ChatGPT-6 Astra. Non \u00e8 certo perfetto, come ha fatto notare <a href=\"https:\/\/x.com\/JuanR_Salgueiro\/status\/2096385404450599008\">Juan Ram\u00f3n Salgueiro<\/a>; aggiungo che almeno al mio orecchio \u00e8 abbastanza palloso, non solo Bach avrebbe fatto molto meglio ma anche i compositori minori dell&#8217;epoca ce l&#8217;avrebbero fatta.<\/p>\n<p>Detto questo, il risultato \u00e8 comunque incredibile visto che non penso che questi sistemi abbiano un modello per la musica. Io, fedele al mio motto &#8220;tutto e male&#8221;, scrissi tre corali tra il 1999 e il 2001. Li trovate <a href=\"https:\/\/xmau.com\/musica\/spartiti\/\">sul mio sito<\/a>: prima o poi li convertir\u00f2 in Lilypond cos\u00ec il MIDI verr\u00e0 fuori meglio. \u00c8 vero che non ho studiato seriamente armonia, conosco solo le regole di base, ma sarei stato bocciato perch\u00e9 sono pieni di quinte e ottave nascoste (quelle parallele spero di averle tolte tutte), che nella musica classica sono un peccato mortale. Insomma ho un&#8217;idea di cosa si pu\u00f2 fare e cosa no con la musica, e vi garantisco che avere un corale funzionante non \u00e8 banale&#8230;<span hidden class=\"__iawmlf-post-loop-links\"
