Working in silence, or nearly so, can free you from distractions. I always used to get a tremendous amount of painting done overnight, during deadlines at school when something had to be done for the next morning. Often, I’d end up working through the night, staying awake to finish a piece for class.
But while deadlines can be harrowing, there’s inspiration to be had when working alone. If you don’t have a studio to retreat to, it can be a similar feeling to have the place you live all to yourself, when everyone else is asleep. It’s just you and your work, you listen to the piece, it speaks to you, and your conversation goes on, in feelings and impressions rather than words.
Sometimes it’s helpful to pull an all-nighter, even when you don’t have to. Experiencing the quiet space around you is both calming and sense-heightening.
