Thies Roorda studied at the Royal Conservatory in The Hague with Paul Verhey and in the United States with the renowned Geoffrey Gilbert.

He is flutist in the Dutch Radio Philharmonic Orchestra and a prolific player of chamber music in various kinds and styles. Many years, as a member of the Hummel Trio, he, along with pianist Mila Baslawskaja and cellist Dmitri Ferschtman, dedicated himself particularly to Classical and early Romantic repertoire. At present he is involved in recording projects of late romantic music (Complete works of Sigfrid Karg-Elert) with Georgian pianist Nata Tsvereli. It is also she with whom he plays on his recently released CD Beyond late Romanticism, featuring works by Max Reger, Sigfrid Karg-Elert, Volkmar Andreae, Ernst von Dohnanyi and Frank Martin.

Several Dutch composers dedicated works to him, a/o.: Maarten Bon, Joep Straesser and Konrad Boehmer. But also foreign composers wrote for him, amongst whom Isang Yun and Jean Françaix. With the latter, he recorded the Divertimento for flute and piano, accompanied on the piano by the composer in person. Furthermore, he made CD recordings of works of Isang Yun and Giacinto Scelsi and Rudolf Escher.

Thies Roorda is especially known for the way he teaches the expressive qualities of the flute sound in all its aspects. His successful approach that allows his students to find their own ‘voice’ on the flute, resulted in a much sought after course on - as he likes to call it - the ‘Blow How’ of the flute, a course which acknowledges the role of the breathing apparatus in all motoric functions of the human body and approaches breath control in an integrated way.
