I seem to remember that Stravinsky used to pin his manuscripts to a wall so that he could see through time. I understand why he might have done that, though to me it feels more like a pilot’s view of an airport and runways BEFORE actually selecting a specific runway to land on. For several years now, I’ve enjoyed (learned-new-things-from) laying a piece out into a line of several pages and looked along the pages from the most recent to the earliest in view. Depending on the speed of the music, what I see (especially if I put my face to a low altitude as though the music is the ‘runway’ I am about to land-on), might be a few seconds in musical time or a longer period of acoustic events.
Perched on the cliff at the edge of a valley somewhere, I see a track down the cliff-wall and how it bends and weaves through a tapestry of changing habitats on the valley floor. It’s like reading a map I might follow except that this isn’t cartography- it’s an eagle-eye view of where I’m going. Somehow- deliberately putting myself into an unusual position to view things is very close to putting myself into an unusual position to hear things.
Even looking down the fingerboard and frets of a guitar seems to me to offer a new insight(sounds) into the notions of low-to-high-notes!
