Suzuki Violin School recordings are widely available. The first books you will need are Suzuki Violin School Book 1, the International or Revised Edition (with CD) and Step by Step Volume 1A by Kerstin Wartberg (with CD). I suggest either buying from SHAR (www.sharmusic.com) or Amazon (SHAR sells on Amazon). Instant downloads are available through Amazon.com and iTunes. Be sure you know what volume you want to buy and that you buy the most recent recordings which were done by William Preucil for the revised Suzuki editions or Hilary Hahn for the international editions.
