Rev up your bass engine with the innovative approach of the BASS MATRIX. No worries about reading sheet music: the BASS MATRIX notation is as intuitive as that of a drum machine. It shows exactly where each note is placed and how long it should sound – so no sight-reading skills required.

Looking for a stylish bassline? Each bassline and rhythm is based on a grouping. In the ‘BASS MATRIX,’ we explore numerous famous basslines and bass-and-drum patterns across various styles, from 4/4 to odd meters. We uncover their rhythmic foundations and see how these groupings are then filled with tones. This way, you can learn to develop your own signature basslines, solidifying your sense of rhythm and groove like never before.

With the intuitive Bass Matrix method, you’ll achieve in-the-instant progress and suddenly be able to play things you never thought possible before. BASS MATRIX helps you to build up your own groove and fill repertoire, which you can use in all situations to play in a song-oriented, solid and tasteful way – just as you need it for your everyday bass playing. The book is organized into six toolboxes that cover six aspects of bass playing – you can start right where you want. Presented in a form that is suitable for beginners, advanced players and pros alike.

Guided by the renowned bassist Philipp Rehm and together with drumming icon Ralf Gustke, BASS MATRIX leads you into new and unexplored musical territories that you will love. Grab your instrument, make yourself comfortable and let’s rock together!

Opinions from the Bass Matrix

"I've only just started to get to grips with the content, but I can already say that it's fun and motivating." ... "The purchase was a good decision."

Review on

"I came across the Bass Matrix on YouTube and although I've been playing electric bass for 30 years and play from both sheet music and tabs, there are lots of new rhythmic ideas and explanations at the start, which are supplemented by YouTube links. Absolutely recommended to buy!!!"

Customer rating on AMAZON

"Beginners, intermediate players, professionals – everyone gets their money's worth. You don't even have to be able to read sheet music, as Rehm has devised a new notation system specifically for this book, which is intuitive and therefore quick to adapt to."
