Dennis Jeter began playing the trumpet at the age of 16 after attending a Wynton Marsalis concert in Washington, DC. Soon after, he was accepted into the Peabody Preparatory program in Baltimore, MD to study with Wayne Cameron. In the spring of 1987, he graduated from the Duke Ellington School of the Arts in Washington, DC with honors and later was enrolled as a computer science major at the University of Florida on a full merit scholarship. While attending the University, he participated in their marching band and held the principal trumpet chair in the symphony orchestra. In the Summer of 1987, Mr. Jeter was the recipient of the first Wynton Marsalis scholarship to study music at the Eastern Music Festival in Greensboro, North Carolina. The following year, he transferred to the Manhattan School of Music in New York City, NY to study trumpet with William Vacchiano. While at the Manhattan School, his interest in the music industry broadened and he soon became very active in the business of music. In the Fall of 1990, Dennis was sponsored by William Vacchiano to become a Yamaha Young Performing Artist.
In the Fall of 1991, he joined Horizon Concert Artists which is an organization that performs recitals in schools, homeless shelters, AIDS hospices, and elderly homes around New York City. Also in 1991 he founded a not-for-profit organization called the Carmagniole Consortium. This organization served as an umbrella for a 60 member orchestra, brass ensemble, brass quintet and string orchestra. The groups performed regularly as a part of the Chelsea Concert Series founded in 1992 by Mr. Jeter to serve as presenter for the Consortium projects. In the Spring of 1991, Mr. Jeter graduated from the Manhattan School of Music to pursue a career in music performance. He has been presented in classical recitals throughout the United States as well as major jazz venues in the New York area including the Miles Davis Tribute in 1992 at St. John the Divine in which Mr. Jeter was a featured performer with the Max Roach Brass Quintet. In 1994 Dennis started the 'Monday Night Jam Session' at The Iridium in New York City which ran for eight months. Many of today's young lions found their way to the Iridium on Monday nights including Wynton Marsalis, Roy Hargrove, Nicholas Payton, Wes Anderson, Marcus Roberts and even Lionel Hampton.
