A native of Amsterdam, the Netherlands, Diederik van Wassenaer attended the Conservatory of Amsterdam before moving to Bloomington, Indiana, where he earned a Bachelor in Music at Indiana University's Jacobs School of Music in 2013 studying with Mark Kaplan and Nam-Yun Kim. Diederik also holds a Masters in Music from Codarts University of the Arts in Rotterdam, the Netherlands, where he studied with Gordan Nikolitch. 

As an orchestral violinist, Diederik has regularly performed with the Belgian National Orchestra, North Netherlands Orchestra and Sinfonia Rotterdam, among others. 


Diederik is a member of the Rotterdam-based Laurens Trio with pianist Lieselotte van Tol and cellist Belén Méndez Valledor, which has played concerts across The Netherlands and were 2020 finalists in De Grote Kamermuziek Prijs, an annual chamber music competition held in The Hague.

One of his most recent collaborations include 'Bach Clinic', a concept developed by Dutch cellist and theater-maker Jacqueline Hamelink, which provides unique one-on-one concerts featuring the solo instrumental works by J.S. Bach. 


Diederik frequently collaborates with Dutch singer-songwriters and cabaretiers J.P. den Tex, Paul de Munnik en Kees Prins, performing dutch translations of classic songs by Bob Dylan, The Band, Joni Mitchell, Neil Young and others in theatres across the Netherlands. 

Diederik has arranged and recorded strings on critically acclaimed albums for bands and solo artists in a wide range of genres as well as recorded for film and video game soundtracks at Nashville's famed Ocean Way Studios. His recording credits include work with Peter Oren, Busman's Holiday, Tristen, Steve Marino, Harpooner, Dead Horses, Somos, Lil' Bub, Hanna Benn, Tim Grimm and Ben Bedford.

Equally at home playing the fiddle, Diederik enjoys twin fiddling with his talented fiddle-wielding fiancée Allie Summers and has been a long-time member of the Bloomington-based folk group 'Wonderhills'. He has also collaborated with Indiana University's Silk Road Institute as well as with the Lithuanian singer Maria Krupoves, performing folk songs from Eastern-Europe and Central-Eurasia. 


Also an avid songwriter, Diederik fronted the Bloomington-based rock band 'Dietrich Jon', releasing the EP 'Higher' in 2014 and their debut full-length 'Too Much' in September of 2017.
