I’ve used a lot of tricks to keep myself focused on writing (not always successfully.) Some of my books have whole musical playlists, a kind of unofficial official sound track that I can sometime use to put me in the right frame of mind. Sometimes though, it seems as much a distraction as a help. Lately I’ve been playing with increasingly popular idea of using sounds that suppress the limbic system, thus allowing me to concentrate.
I’ve grown quite fond of a combination of methods, namely the site above, Focus@Will, which has both free and subscription services. They are a small start-up and thus very worthy of love, but I’m also fond of their customer service: when users complained that a popular beta feature had been removed, it took less than 24 hours for them to have to feature returned. Now that’s responsive.
The second web site I find myself using a great deal is Coffitivity, a free beta service which does nothing more or less than sound like a coffee shop. Combined with Focus@Will, I can imagine I’m in a quiet corner of my favorite shop with some nice music playing, and the words flow. I usually need to adjust the volume on both (you want the volume quite soft to emulate ambient noise rather than listening music) but once they’re in place, I’ve found it incredibly useful.
Your mileage may vary of course. My SO prefers to listen to loud music with parallel themes to what he’s writing.
