I play mainly acoustic bass guitar or electric bass guitar.

This is my fretted bass, build by luthier Kenneth Brøgger

I practice (and struggle with) J. S. Bach’s Cello Suites every day. It has helped me to build up technique, overview, sound and touch of my instrument as well as it has opened my mind and improved my skills as a composer. If you play bass and have time and patience enough I strongly recommend this. If I get response to it, I will gladly upload more files.
