If you are a serious composer you can do no better than Sibelius which allows you to write down any music you would ever want. It is worth a look as it does great student deals. But if you just want to dip your toes in, for all you budding composers – there is a free and comprehensive programme available for writing music at Muse Score. It may look a little daunting at first, but there is lots of information about it and instructions. Really it couldn’t be better!! Do give it a go!
