The core Suzuki literature is published on audio recordings and in sheet music books for each instrument, and Suzuki teachers supplement the repertoire common to each instrument as needed, particularly in the area of teaching reading. One of the innovations of the Suzuki method was to make quality recordings of the beginners' pieces widely available, performed by professional musicians. Many traditional (non-Suzuki trained) music teachers also use the Suzuki repertoire, often to supplement their curriculum, and they adapt the music to their own philosophies of teaching.
Another innovation of Suzuki was to deliberately leave out the large amount of technical instructions & exercises found in many beginners' music books of his day. He favored a focus on song-playing over technical exercise, and asked teachers to allow students to make music from the beginning, helping to motivate young children with short, attractive songs which can themselves be used as technique building exercises. Each song in the common repertoire is carefully chosen to introduce some new or higher level of technique than the previous selection.
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.
