This second set (Nos. 21 to 38) from the 60 piano studies by C. L. Hanon are, along with Part 1, an important part The Virtuoso Pianist. 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. Also included with Part 2 are the twelve Major and minor scales, chromatic scales, diminished and dominant 7th chord arpeggios, and two of the most significant exercises from Hanon's studies, Part 3 – scales in thirds, and chromatic scales in thirds.
