Finding value in an unsuccessful first version

Text A: an original contemporary practice extract.

My first home-recorded song sounded distant and thin. I nearly deleted the file after listening once. A friend asked me to keep it until we knew why the words were hard to hear. We compared it with a short recording made closer to the microphone and discovered that the room had become more prominent than the voice.

The next version was clearer, although the song still needed work. I retained the first file with a note about the microphone position. It was not a hidden masterpiece I had misunderstood. It was a record of one arrangement that did not serve the song, and keeping it stopped the next attempt from beginning with the same guess.

Text B: an original contemporary practice extract.

The youth group’s first model bridge sagged under the weight used in its classroom test. Two members wanted to dismantle it immediately and begin again. The group leader asked them to photograph the joins and draw where the bend had started before removing anything.

A revised model distributed its support differently and held the test weight for longer, though one joint still loosened. The first drawing stayed beside it. Nobody displayed the failed model as if failure itself were an achievement. Its usefulness lay in evidence of what needed changing. The group could explain why the second arrangement differed instead of simply announcing that it was better.
