Discordant

I was catching up on the messages on a conferencing system by flicking through the unread messages when I came across the following comment:

> Isn't C -> C#m a bit of a wrench?

Which had me wondering what the hell the computer language C#m was and why the hell anyone would think the world needs yet another flavour of C to contend with when I realised that it was a music conference and they were talking about chords...
