These early-intermediate etudes by Louis Köhler (1820-1886) emphasize five-finger patterns, scale passages and broken chords, and are set in imitative and melody and accompaniment textures. All fit well under the hands and assist less-experienced players with legato and staccato articulations and phrasing. The foreword contains Köhler's practice suggestions from the original edition. An excellent choice for a first etude book.
