These first 20 of the 60 piano studies of this set by C. L. Hanon are the most popular etudes ever written. Hanon's goal: "Preparatory exercises to acquire speed, precision, agility, and strength in the fingers...(and) flexibility of the wrists." The etudes enable students to focus on playing patterns with a relaxed hand while supporting the fingers with the hands and arms. They also make a wide range of finger patterns easy for pianists to recognize and execute when learning and accomplishing repertoire. This finely engraved edition eliminates clutter and has logical "turn arounds" as the note patterns change direction.
