Jon Rose - Concert Hands Music Composer

Jon Rose

Although living near Boston made Berklee School of Music the obvious choice, Jon chose to audition for and attend the University of Miami School of Music in Coral Gables, Florida. There he received a Bachelor of Music in Jazz Piano under the instruction of Vince Maggio (former students include Bruce Hornsby, T. Lavitz, and Mike Gerber). Prior to graduation, Jon was already making connections outside of the University and playing gigs at South Florida venues. While the demand for his services steadily increased, he continued his education and received a Masters of Music in Media Writing and Music Production under department head Raul Murciano PhD.

Jon's hallmark is his versatility in performance, style, and production capabilities. By playing solo piano jobs for many years, he has amassed a wealth of standard songs and showtunes in his vast repertoire. He also has performed in and assisted with several musical theater productions such as
Rags, Hairspray and Chicago. Jon's credentials span from being a solid pit orchestra musician to writing arrangements for major shows. He also is a highly sought-after accompanist. Jon has played with many acclaimed recording artists such as Jon Secada, Tony Sandler, and Christian Castro in shows that have varied in size from intimate gatherings to major performance arenas.

While living in Miami and absorbing the city's cultural diversity, Jon has added various latin piano styles to his bag of tricks. Not about to be pigeon-holed into one or two styles, Jon recently toured the US and abroad playing rock organ and singing background vocals for teen heart throb and Columbia Records recording artist
Teddy Geiger. Jon is also an accomplished arranger, most recently having written string arrangements for a Ricky Martin CD/DVD, and for Tito Puente Jr. symphonic dates. Jon's production credits include the composition and production of three jingles for a beverage called BAWLS. He also wrote and produced theme songs for two prominent Miami-based television shows.

Jon's most recent projects include playing keyboards for Sony recording artist Alicastro, as well as touring with Jon Secada as his pianist/keyboardist.
