My husband and I listen to music completely differently. I just wander away into it, no real thoughts, just feelings. I like music when it's familiar, I've heard it a couple of times. He listens to it, for want of a better cliche, with his head, admiring how it was written, performed, the technological efforts that produced it. He loves new music. He also loves radio plays, just sits there and enjoys them (or occasionally doesn't) depending on the subject and the play itself. I don't seem to be able to listen and engage my brain at the same time (oh, this explains a lot of my school experiences!). On the other hand, he looks at text and gets slowly bored. He likes short sections of text, possibly autobiographies, preferably the shortest writing for the maximum information. Reading bores him, listening is easier for him. I hate course CD's and download the transcripts. I like long books, big stories, and get immersed in them.
When I'm writing, I 'hear' my characters' dialogue very distinctly. I see the locations (though my characters are a bit iffy, I describe them when I remember from actors' bios and pictures). The words, as read visually, have music for me, they build up lovely sequences of sounds and meaning. Reading them aloud makes them sound stilted and slow to me. Yet my radio play efforts sound clear in my head at the speed at which I can type them. It's only when I come to read them that they look odd.
One of the advantages of A215 is that I can look globally at my writing and judge whether it's good or not (at least, when I don't have a deadline looming). And, bizarrely, the radio plays are good. It makes you think about realistic dialogue, expressing more of the story in less cues. It's a very helpful exercise. Defining not only who the character is without any visual cues or internal thoughts, but also their emotions and ideas entirely in speech or sounds is a fascinating exercise.The BBC encourages people to submit scripts, even if they are the wrong length etc. and are willing to allow a bit of devlopment of a promising radio writer, by the sound of it.
It's all taking my mind off the move in a couple of weeks time, anyway!
