And here's a bit more detail about the three main ways to find things online:

The grey navigation bar just below the top of the screen:

If you're looking for a particular show, click 'Programmes' and type its name. Browse programmes by genre from the 'Categories' menu or use the schedule to locate a programme directly.

Just below the grey navigation bar, the meat of the new web site:

Here you'll see details of the programme that's on-air now plus the next one and the one after that. Click the big grey arrows at left and right to flick through panels of information about the station's output: highlights selected by us, the top programmes for online listening and other content we're featuring. This is regularly-changing content where you can get a sense of what's going on at Radio 3 right now and this week.

Further down the page you'll find a panel of boxes:

This is where you'll find links to all the important Radio 3 stuff - our newsletter, the blog and social media and to the A-Z index of composers, for instance. We'll also put links here to big seasons and to the BBC Orchestras.

Click the 'What's New?' link in the grey navigation bar for a visual guide to the new Radio web sites. Use the hashtag #bbciplayerradio if you're discussing the new web sites and the app on Twitter and follow @BBCiPlayerRadio for news and information.

Mark Friend, Controller of BBC Radio's interactive department, has written a post for the BBC Radio blog about the changes. Let us know what you think of the new design by leaving a comment on his blog post.
