Heller's Opus 45 is a set of 25 short character pieces, where each piece focuses mainly on a specific mood or technical challenge. The level of creativity and artistry in these works will help you develop not just your technique but most importantly fluency and musicality. The dotted rhythm is the most defining feature of this piece which involves not just timing but also a very specific shape of sound. The character is confident, uplifting and the technical challenges are primarily on the right hand.
