Iris also plays the early music version of the trombone: the 'Sackbutt'
The first time she heard the instrument, she felt in love with the beautifull warm and soft sound of it, which turned into the desire of playing this instrument as well. After doing the 'fiori musicali' summercourse in Utrecht given by the 'Ceacilia concert' in 2012, she ordered an instrument from Geert-Jan van der Heide in Putten, specially build after an instrument from Sebastian Hainlein 1630 Nürnberg.
She started to have some privat lessons and ensembles on this instrument. Since 2014 she is playing with ensemble 'Vento Vivimus' and she desided to start also with Alto- and Bass-sackbutt.
Her interest for early music was immediately there from the first moment she ever heard it. As a child Iris started with playing recorder, what in fact never flew over when she started to play trombone so she has always had a connection with early music. This connection increased when she in 2011 started again with having recorder lessons. When she discouvered the existance of the sackbutt she immediately knew this was the way to be able to play early music on trombone.
Iris always has had interest in history what she also wants to emphasize in her performances of early music. "It is important to do research after the music you play so you have the possibility to come as close as possible to the performance they would have liked at the time where the music is from, therefore it is important to look after books from people from that time and look after facsimilae. There are a lot of thing that are lost in modern editions which causes problems and discussions during rehearsals. Mostly a lot of these things can be solved by using the facsimilae, because the notation fits the music. except for that reading from handwritings is very inspiring for me"
At the moment Iris is working on some facsimile editions herself for her own ensembles. These editions will be published on this website under compositions and arrangements.
"my most impressive early music moment was when I heard the 40 part mass of Striggio being performed at the 'festival oude muziek' Utrecht. "
