Instead of a review this week here’s another installment in the Kopprasch Project. No. 56 will test your agility and flexibility (in arpeggiated and stepwise patterns) through a two and a half octave + range. Suggested tempo in my edition is dotted-quarter=72-96, and dotted-quarter=ca. 80 seemed to work for this recording. The most challenging part of this study for me was centering isolated staccato notes, particularly when leaping downward from a note in or above the staff. B-flat fingerings seemed to help for the notes just below the staff.  For the compound interval leaps in the last five measures experiment with different jaw and tongue positions to help negotiate them.
