My practices almost always go better when I have a story to imagine while I am playing.
Think of the impact that music has had with the stories of cinema. You won’t hear “Darth Vader’s Theme” and not think Darth Vader. Similarly, make your music describe a story from your life, a favorite novel you love, a story from a book of scripture if you are a musician of faith, or just make up a story of your own.
Write little sentences describing your story in different parts of the score to help you remember in future practice sessions. And if prompted, don’t hesitate to share your story with your audience if you feel it will help them connect more to the music!
