Will Hartmann studied at the Musikhochschule in Cologne and has won prizes at several well reputed singing competitions. He began his career as a lyric baritone, taking up an engagement in the Opera Studio at Cologne Opera in 1991 and becoming a member of the ensembles there in 1993. Then from 1996 to 2006 he was a member of the ensemble of the State Opera in Hannover. Will Hartmann's first successful sorties into tenor territory date to summer 1998 when he made his debut at the Royal Opera House in London as Da-Ud in concert performances of Richard Strauss's opera Die ägyptische Helena under Christian Thielemann. The official changeover to tenor came in 2000, whereupon he made debuts in a number of roles at the State Opera in Hanover. His debuts as Pelléas and Alfredo were internationally acclaimed. At Graz Opera in 2001 he made his debut as Lensky under Philippe Jordan. In 2002 he sang Macduff at the Royal Opera House in London and also sang Tamino in a new production of The Magic Flute there in early 2003 under Sir Colin Davis. His debut at the Bavarian State Opera in Munich followed in 2002 (Jenik) and his Vienna State Opera debut in 2004 (Tamino). He performed as Pelléas at the Vienna Festwochen and the Edinburgh Festival. His performance as Froh in the new production of The Ring at the Royal Opera House in London (Warner/Pappano) in late 2004 was judged a great success. In summer 2006 he made a highly impressive debut as Loge in a new production of The Rhinegold by Graham Vick at the Teatro Sao Carlos in Lisbon. In the same year he attracted attention with his interpretation of Don José in a new Carmen production by Sebastian Nübling at the State Theatre in Stuttgart. In 2007, Hartmann made his Deutsche Oper Berlin debut in the role of Max followed by his Berlin State Opera debut in the same role a short time later. In summer 2008 he was involved in a revival of the legendary Freischütz staging of Achim Freyer at Stuttgart State Opera. Guest appearances have taken him in recent years to Leipzig, Dresden, Rome, Paris, Madrid and Athens as well as to the Festival in Orange. He has been performed in radio and television broadcasts under conductors like G. Sinopoli, M. Janowski, M. Honeck and S. Cambreling. Most recently Will Hartmann appeared as Don José at the Royal Opera House, as Matteo at the Munich Opera Festival, as Melot in Tristan (Chéreau/Barenboim) and as Daniló in Die lustige Witwe, both at La Scala Milan.
