Suzuki teaching uses a common core repertoire for students of the same instrument worldwide, and although it focuses on Western European "classical" music, it emphasizes that this music can be a bridge across cultural and language barriers: one does not have to share the ethnic or national origin of the composers in order to learn or share the music. Suzuki created a series of rhythmic variations on the theme "Twinkle, Twinkle, Little Star", using rhythms from more advanced literature in units small enough for a beginner to grasp quickly. Although these variations were created for violin, most of the instruments use them as a starting point for their repertoire.
