Erutan performs and arranges her work by herself, being able to play the violin, the piano, the lyre, the guitar, several types of drums, and an array of other musical instruments. If the theme she covers lacks lyrics, she writes them herself, keeping in mind the mood and atmosphere of the tune. Her equipment includes a simple vocal microphone, a closet (as her "dead room," which she had recently renovated to become a sound-proof recording studio) and the Sony Vegas Pro video and audio software to mix her tracks. Kate has never received vocal training, but is a trained professional violinist, which she claims helps her pick up other instruments more easily.
