Slow Writing

Before there were copy machines, online music sources and recordings, musicians had to copy scores by hand. Musicians from those times who needed to do this reported that they generally knew the piece before they came to play or sing it. In addition, they knew then also how to read and often memorise music on sight. What this meant was that they did not need to both read the music and coordinate themselves at the same time, but had fine-tuned their nervous systems to receive and process the music, which made the release of it into movement, breath and sound much simpler and clearer.
Expressivity and technical advancement can come for free, from first slowing your brain down and writing the music by hand. For singers, writing the text in your own handwriting is similarly useful. When you are writing, you increase your chances of being able to coordinate yourself when you play, if stay calm and work slowly. Don’t stare at the paper or rush to do a lot, but look around the room or out the window every now and then, and even when looking at the paper, keep your peripheral vision open. Even 15 minutes of this kind of practice, writing down one section of music, can fine-tune your musical brain and improve your playing.
