Personal annotations
Yehudi Menuhin, a great violinist, marked up a score for Bach's Sonata No. 2 for Solo Violin. Penciled annotations show real-time performance strategies. To outsiders, insider markups appear chaotic and cryptic, but these personal annotations are for Menuhin's eyes, the only eyes that matter. All can learn from this useful workaday grid strategy: a relevant and intense data layer can become a coherent substrate scaffold upon which to overlay additional information. Maps do this all day long.
Time and space
Tones appear placed and directed predominantly in time from before to now to later.
Their juxtaposition in a musical composition is perceived
within a prescribed sequence only.
Horizontally, the tones follow each other,
perhaps not in a straight line, but of necessity in a prescribed order
and only in 1 direction – forward.
Tones heard earlier fade, and those farther back disappear, vanish.
We do not hear them backward.Colors appear connected predominantly in space. Therefore,
as constellations they can be seen in any direction and
at any speed. And as they remain, we can return to them repeatedly
and in many ways.
This remaining and not remaining, or vanishing and not vanishing,
shows only 1 essential difference between the fields of tone
and color.The accuracy of perception in one field is matched
by the durability of retention in the other, demonstrating
a curious reversal in visual and auditory memory.
