Trombone performance and pedagogy


Andrew Glendening is the Dean of the School of Music and Professor of Trombone at the University of Redlands. A native of Logansport, Indiana, he earned a Bachelor of Music degree in Trombone Performance from the Oberlin Conservatory of Music before attending Indiana University where he was awarded the school's highest honor: the Performer's Certificate. He also earned a Master of Music degree and was the first ever to receive the Doctor of Music degree in Trombone Performance from the Indiana University School of Music. His primary teachers were M. Dee Stewart, Per Brevig, Thomas Cramer, and Frank Crisafulli. Prior to becoming Dean at Redlands, Dr. Glendening was Chair of the Department of Music at Denison University and served on the faculties of Morehead State University and Northeastern Illinois University.

An active innovator in inter-active music, Dr. Glendening has premiered, performed and recorded many works for computer and instruments and has lectured on inter-active applications at such institutions as the CNMAT Laboratory at UC Berkeley, CEMI at the University of North Texas and the Eastman School of Music. He is also the inventor of the "Magneto-restrictive slide position sensor" for the trombone, which allows for direct integration of the trombone and a computer using MAX/MSP software both for performance and pedagogical study.

An active proponent of new music for the trombone, Dr. Glendening has premiered over 100 works, including three concerti. In 1998 he was awarded Morehead State University's Distinguished Creative Productions Award for his solo CD, "Pathways: New Music for Trombone" (Mark Records.) He premiered the wind ensemble version of Robert Parris's Trombone Concerto with the U.S. Army Band "Pershing's Own" in 1999, was the featured performer at the 4th Annual American Music festival in Sofia Bulgaria, performed the Rouse Trombone Concerto with the Redlands Symphony Orchestra in 2008 and performed a recital at the 2014 International Trombone Festival at the Eastman School of Music. He is Principal Trombonist of the Redlands Symphony Orchestra and has performed as a substitute with the Chicago Symphony Orchestra, the San Diego Symphony Orchestra and the California Philharmonic. Six of Dr. Glendening's trombone students have won the U.S. Army Band National Solo Competition.

In 2017, International Music Diffusion published his book, co-authored with Julia Broome-Robinson, “The Art and Science of Trombone Teaching” in both English and French. Dr. Glendening was host and artistic advisor for the 2017 International Trombone Festival.
