At Henle 5 this is a late-intermediate piece — technically substantial, with musical demands to match. The main demands: sweeping arpeggio figures that must stay smooth across positions; a true singing tone, with the melody floating above the accompaniment; and ornaments that need to sound effortless, not squeezed in.
Beyond that, expect fast passage work that stays light and even at tempo.
Mastery of smooth, elegant arpeggio shapes is essential to create the fluid, sparkling sound required by Smith's writing.
