Composer
Thierry Roggen's compositional style is always committed to the traditional classical-romantic sound aesthetic. As a four-year-old, he already writes small compositions, at that time mostly in the baroque style. At the age of eight, he composes several fugues and often improvises for hours at the piano.
In September 2000, Thierry won 1st prize at the Swiss Youth Composition Competition, and also the audience prize at the presentation of his "Tageszeiten" for double bass and string quartet (published by Musik HUG). His fantasy "Hommage à Paul Klee" was premiered with great success at the Bach Festival 2005 in Bern. In 2008 and 2009, the "Jeunesses musicales Orchestra" premiered his work "Images" under the direction of Srboljub Dinič, and the Swiss army Brass Band premiered his "Sinfonietta for Brass Band" in a tour of Switzerland. However, Thierry received the finest moment in composition for his "Andante for String Orchestra". At all three performances with the orchestra of the "Bayerische Philharmonie", the audience gifted him with standing ovations.
Arranger
In summer 2011, Thierry reconstructed the orchestral part of a presumably forgotten double bass concerto by Johann Matthias Sperger. A concerto of which neither a basso continuo nor orchestral material existed, but only the solo part. After its completion, it was performed for the first time at his final soloist concert in Freiburg i.Br (D) with the Kurpfälzische Philharmonie Mannheim.
His arrangements also include curiosities, such as the arrangement of the sixth Brandenburg Concerto by J.S. Bach for six double basses and harpsichord, or Elvis Presley's hit "Can't help falling in Love" for double bass and harp.
