Hi KQED,

0:00:01.862,0:00:03.848
my name is Stephen Malnowski.

0:00:03.848,0:00:06.047
Let me tell you what I've been making.

0:00:06.978,0:00:09.594
A while ago, when I was learning to read music,

0:00:09.594,0:00:11.826
I could follow the score for a single instrument

0:00:11.826,0:00:15.378
[violin playing]

0:00:18.490,0:00:21.234
much more easily than a score with many instruments.

0:00:21.234,0:00:24.104
[orchestra playing]

0:00:26.491,0:00:28.889
To make complex scores that were easier to read,

0:00:28.889,0:00:32.930
I condensed them by putting all the notes on a single staff,

0:00:32.930,0:00:34.837
like in piano music.

0:00:34.837,0:00:39.593
Unfortunately, this made it hard to see which instrument was playing which note.

0:00:39.593,0:00:42.470
I tried coloring the notes by instrument.

0:00:42.470,0:00:46.354
That worked better, but since all the note symbols were about the same size,

0:00:46.354,0:00:51.193
a long note for one instrument could easily be lost among shorter notes of other instruments.

0:00:51.193,0:00:54.137
The solution was to use bar graph notation.

0:00:54.137,0:00:57.145
At first, I drew paper scrolls by hand,

0:00:59.974,0:01:02.688
but later I learned how to make them with computer software.

0:01:02.688,0:01:06.761
The first version, on the Atari 800, looked and sounded like this:

0:01:06.761,0:01:10.149
[electronic song plays]

0:01:26.325,0:01:30.630
The second one, on an IBM PC, looked like this:

0:01:30.630,0:01:35.858
[harpsichord arrangement]

0:02:03.118,0:02:06.379
Over the years, I experimented with other ways of showing music.

0:02:06.379,0:02:09.764
[classical piano playing]

0:02:23.416,0:02:26.134
[Beethoven's 5th Symphony]

0:03:04.092,0:03:04.092
[adagio piece]

0:03:26.138,0:03:29.162
[allegro violin]

0:03:43.130,0:03:45.943
[Bach's Cello Suite #1]

0:03:54.561,0:03:59.656
Recently a violinist told me he wanted to use my visualizations in live performance.

0:03:59.656,0:04:04.307
So I made a version of my software in which the timing of the animation is controlled with a crank.

0:04:07.713,0:04:10.058
We tried this out with the symphony orchestra.

0:04:10.058,0:04:12.254
It worked.
