Nature I have constantly argued in my work is the real superpower of this godless universe. It is the ultimate disposer of human fate randomly recarving geography over 10 000-year epochs.

My husband is a composer so he plays piano all the time and I sit there and clap telling my unborn child 'Hear me clap hear the music.' I know music in general is supposed to be good for babies to hear.

I got interested in the idea of music that could make itself in a sense in the mid 1960s really when I first heard composers like Terry Riley and when I first started playing with tape recorders.

Composers shouldn't think too much - it interferes with their plagiarism.

If a composer could say what he had to say in words he would not bother trying to say it in music.

It's hard to decide how to match words to music. It's not like it's twice the work. It's always difficult for me to explain to the composer what I'm looking for. I'm not a professional I lack even basic knowledge about writing music.

Music is at once the product of feeling and knowledge for it requires from its disciples composers and performers alike not only talent and enthusiasm but also that knowledge and perception which are the result of protracted study and reflection.

Have you heard of this new thing called the internet? It's giving people new expectations. It's allowing them to become their own expert. Knowledge lies anxious at their fingertips. Gloss over the truth in your advertising and you'll quickly be dismissed as a poser.

My musical knowledge is so bad it's embarrassing. When composers discuss music with someone as primitive as myself they have to talk about it in terms of senses and emotion rather than keys and tempo.

I have learned throughout my life as a composer chiefly through my mistakes and pursuits of false assumptions not by my exposure to founts of wisdom and knowledge.
