Even when incorporating different genres and influences, it's crucial to have a strong foundation in Rock music. Start with a solid Rock groove, riff, or chord progression as the basis for your song. When incorporating different genres, choose ones that are compatible with Rock music. For example, Blues, Funk, and Punk are genres strongly tied to rock music. Experiment with different instruments and sounds to add new textures to your Rock song. For example, incorporating horns or keyboards can add a Funk or Jazz element, while adding electronic elements can create a more modern sound.
