Motion
Mouvement
La musique électroacoustique est un art du temps au point qu'elle ne peut être appréhendée d'une manière appropriée qu'à travers des métaphores du mouvement et de l'évolution. En effet, les concepts traditionnels de rythmes sont inadaptés pour décrire les contours souvent dramatiques du geste électroacoustique et les mouvements internes des textures qui répondent à une grande variété de spectromorphologies. Puisque le mouvement et l'évolution ont des contours spectraux, ils existent dans l'espace spectral. Par conséquent, leur occupation de cet espace et leur densité spectrale sont d'importants critères de description. En outre, le mouvement et l'évolution peuvent être mis en valeur par la distribution spatiale réelle. De plus, ils ont aussi des tendances à nous suggérer des attentes possibles et sont des guides très utiles pour l'attribution de fonctions structurantes. (Résumé à partir de Denis Smalley (1997).

Movimento
Secondo la teoria della spettromorfologia di Smalley, le metafore di movimento (motion) e di sviluppo (growth) sono le più appropriate per spiegare una musica, quella elettroacustica, legata alla dimensione di tempo in modo differente rispetto alle musiche tradizionali più connesse con l'idea di metro e ritmo. Il concetto tradizionale di ritmo risulta infatti inadatto quando si tenti di descrivere i contorni del gesto elettroacustico e i movimenti interni delle tessiture delle varie spettromorfologie. Poiché il movimento e lo sviluppo hanno una connotazione spettrale, il discorso è da collocarsi in una dimensione appunto spettrale, sia per quanto riguarda lo spazio che occupano, che per quanto concerne la densità spettrale. In aggiunta, il movimento e lo sviluppo possono essere intensificati dalla distribuzione spaziale. Essi possono indicare direzioni e tendenze in modo da suggerire vari risultati possibili, e sono guide molto utili per l'attribuzione di funzioni strutturali (tratto da Denis Smalley (1997).

Movimiento
Las metáforas de movimiento y crecimiento son formas apropiadas de considerar a las artes basadas en el tiempo como la música electroacústica. Los conceptos tradicionales de ritmo son inadecuados para describir los frecuentemente dramáticos contornos de los gestos electroacústicos y el movimiento interno de texturas que son expresados a través de una amplia variedad de espectromorfologías. Dado que el movimiento y el crecimiento tienen contornos espectrales, están ubicados en el espacio espectral. Por lo tanto, su ocupación del espacio espectral y su densidad espectral serán también calificativos importantes. Así mismo, el movimiento y el crecimiento pueden ser reforzados por la distribución espacial real. El movimiento y el crecimiento tienen tendencias direccionales que nos conducen a esperar ciertos resultados, y son guías de gran ayuda como funciones estructurales.
