The next step is equally as important to the creative process as the first.
Find a sweet spot. It could be a melody, a groove, a climax, a note, or a chord. Anything that gives you that feeling.
Analyze it, experiment with it and have fun with it! Learn it in every key and at every tempo. For pianists, learn it in your right hand and your left hand. Write tunes based on them. Develop it melodically and develop it rhythmically. Own it!
Find the next sweet spot and repeat. Repeat until you’ve had enough! When you reach that point, you’ll know to move on. You’ll either be inspired to pick another artist or enter a period of output. Compose new music, arrange existing music and share your studies with students and colleagues.
Be prepared to sound a lot like Bill Evans!
