On today's Sound Perimeter, University of Arkansas Music Professor Lia Uribe explores the uniqueness of music that combines beauty and sadness and its ability to reach the core of our humanness. Uribe includes the following pieces of music to illustrate her point: Ludwig van Beethoven's Symphony 7 in A major, opus 92, second movement performed by the Vienna Philharmonic under the direction of Leonard Bernstein, Samuel Barber's Adagio for Strings and Maxence Cyrin's piano cover of "Where is My Mind" by The Pixies. Local artist Tina Oppenheimer has also created a special edition Cheers and Tears greeting card inspired by Sound Perimeter.
