Jerneja Grebenšek je diplomirala na umetniški in pedagoški smeri Akademije za glasbo v Ljubljani pod vodstvom Acija Bertonclja, nadaljevala pa magistrski študij klavirske komorne glasbe na Univerzi za glasbo in upodabljajočo umetnost v avstrijskem Gradcu pri prof. Käthe Wittlich. Vzporedno je nadaljevala tudi specialistični študij klavirja pri madžarskem pianistu prof. Lászlu Báranyayu. Po zaključenih podiplomskih študijih je leta 2005 s slovensko violinistko Mojco Menoni Sikur in violončelistom Martinom Sikurjem ustanovila Klavirski trio Ars Musica. Kot trio so se več let izpopolnjevali pri pianistu Chia-Chiu, nekdanjemu članu Tria Parnassus. V več kot petnajstih letih skupnega delovanja so gostovali na skoraj vseh odrih in abonmajskih sezonah ter festivalih po Sloveniji. Mnogi njihovi nastopi so arhivsko posneti za Radio Slovenija – program ARS, izdali so zgoščenko z deli slovenskih skladateljev. Več kot dvajset let se z veseljem posveča tudi pedagoškem delu na Umetniški gimnaziji v Velenju, kjer poučuje klavir, komorno igro in deluje kot korepetitor. Mnogi njeni učenci, dijaki in komorne skupine so nagrajenci mednarodnih ter državnih tekmovanj, številni pa uspešno nadaljujejo študij na glasbenih akademijah.
