About FretWijzer

FretWijzer shows you exactly which notes you can play in a key, directly on the guitar neck. You can see at a glance where the root notes sit and which notes belong together.

The site is free to use, with no account needed. You'll find all 24 major and minor keys, well-known songs per key, and short explanations of music theory for guitarists.

We're expanding the content step by step, always paying close attention to musical accuracy.
