They say practice makes perfect, so it's worth investing in a range of keyboard and piano books. You can learn your favourite songs and improve your skills along the way. Most come with recordings that you can listen to as you learn – particularly helpful for beginners. Digital pianos feature handy volume controls so you don't disturb anyone else.
Pick your musical instruments wisely when you're ready to start playing in a group. The classics for a rock band are obviously guitars and drum kits, but you might need to soundproof your space if you always turn it up to eleven.
For a more varied sound, you could bring in more percussion with individual drums, or head down the brass route with a selection of trumpets. If you want to practise by yourself and make some cheerful music, a ukulele could be your new companion. Their small size makes them portable and easy to store at home, too.
