Number 57 is an arpeggiated study in staccato articulations, and it is deceptively difficult. Maintaining a centered tone and ringing staccato throughout this etude was a particular challenge for me. The tempo can range from quarter note = 108 – 160, as printed in my edition. Slurring the entire thing is helpful, as is practicing at half tempo. Using B-flat fingerings for notes at the bottom of and just below the staff helped with clarity. A knowledge of harmonic function is important, if not critical, to mastering this etude.
