Some of Gertjan's Sketchbooks

I have stacks and stacks of filled sketchbooks. Here are a few for your viewing pleasure. I initially thought I would narrate this piece and even indicated that in the titles. However, after watching the sketches and listening to the horn concerto I figured that was enough. My talking would not have added much.

I apologize for the sound track. It appears some background noise came into the equation. Nothing serious. This truly is my favourite horn concerto. It's in B flat Major. I composed it in 2018.
