Here are various different tasks to help you get started as we have time away from school. Since we often do practical work in lessons, now is an opportunity to look at researching different styles, listening to lots of music, composing some ideas, and writing about music.
Along with this, if you do play an instrument (or have access to one), look to use this time to really become a specialist at what you do. Perhaps even take up an instrument/singing properly for the first time if you have access to an instrument, and use YouTube to teach yourself how to do it well. I promise you won't regret it and it will be an excellent use of your time that could change your life forever for the better!
