Another challenge was to compose "Authentic" Medieval music. I noticed that many so called "medieval music" soundtracks either used instruments that did not exist in the period like violin sections from an orchestra or a full french horn section, or used harmonies and chords that weren't "discovered" at that time.
And besides doing a lot of research on medieval music, I invested in either virtual or live instruments that were used in that period. I boughta few basic hand drums, an army of recorders, a new virtual instrument which included a Hurdy Gurdy and reed instruments of that time, and also a classical guitar to emulate a lute (an actual lute would have just been way too expensive).
Learning the recorder was an fun experience. I ended up recording only one piece with live recorders because I just didn't make enough progress to make it sound professional. I did play the recorder in school when I was 12, but at the time, I only blew hard in the recorder to annoy my music teacher... Wish she could see me now! :-P
In the full audio pack, I have also included Ambient loops for various settings (forest, castle courtyard, battle...) and a bunch of sound FX. You can check out the in-game demo I've made to showcase some of the sounds available in the pack here:
