Composition in E-flat major by Thiago Minoru Mabuchi is a virtuosic work demanding significant keyboard facility. It utilizes extended arpeggiation patterns common in Romantic-influenced modern writing.
At Henle 6 this is an advanced piece that assumes fluent technique and rewards mature interpretation. The main demands: sweeping arpeggio figures that must stay smooth across positions; wide stretches that reward larger hands and clever redistribution; and fast passage work that stays light and even at tempo.
Beyond that, expect rubato that must breathe naturally without losing the pulse.
Ensure evenness and agility when navigating the wide-span arpeggiated figures.
