I teach bass guitar at my private practice in Nijmegen-Noord (NL). My lessons are 30 minutes at a time and we can study the things you want to learn. That way we keep playing music fun, which is the most inportant thing of all.
It's also possible to learn about music theory. We can do this in combination with an instrument and even without one. A little knowledge of the piano would come in handy, but we can start at the beginning and i can tell you everything you want to know.
I'm also 'Licentiehouder' for the Rockacademie in Tilburg (NL). This means i can help you with the preparations for your audition. If you're interested in this, don't hesitate to contact me!
For more information you can mail me.
