In today's Sound Perimeter with University of Arkansas Professor of Music Lia Uribe, we explore how Frederic Chopin turned etudes from a piece of practice music to stand alone pieces performed in concert halls. We hear Chopin's Etude Op. 10, No. 12 in C minor Revolutionary performed by Evgeny Kissin, Sonido Bestial by Bobby Cruz and Richie Ray, and Wolfgang Amadeus Mozart's Horn Concerto, K. 447, 3rd movement performed by Sarah Willis and the Havana Lyceum Orchestra.
