The SCALE COLOUR SYSTEM is a unique and innovative method to study music that bridges Music Theory and the Mechanics of string instruments.

An intuitive system to map and internalise Notes, Scales and Shapes over the entire fretboard to develop accuracy and to unlock your playing.
The original graphics and illustrations are intuitive tools to visualise and internalise the symmetry of the fretboard – a crucial aspect to mastering the instrument – and to learn music concepts through practical application.



Levels: Beginner to Advanced.

  This system aims to build a strong understanding of music theory and its application on the instrument, to fill some of the gaps that may have occurred during previous studies, and to provide another point of view to look at music.





Alex has devised an inventive system to decode the inherent tonal symmetry of the electric bass. This method demystifies the geometry of the fingerboard and speeds up the process of understanding and internalizing scales, modes and arpeggios. I wish I had a copy of this book when I was starting out!

Alex Lofoco’s Scale Colour System Vol. 1 – Scales is an extremely comprehensive and in-depth approach to virtually every scale that a bassist could be expected to know. He uses an innovative system of using different colours for different scale intervals, superimposed on fretboard diagrams, though notation is also used, and this approach may well suit those bassists who find regular theory books too alien. To master every scale demonstrated would take hundreds, if not thousands of hours’ practice, which probably matches the amount of work that Alex has put into this book! Highly recommended for those wishing to become masters of bass.

A unique, innovative, and refreshing Scale Colour System by Alex Lofoco, which helps the player demystify the fingerboard, scales, intervals, arpeggios, modes and more! A very easy to follow, intuitive and visually instinctual method that bassists of any age and ability can comprehend. If traditional bass method and theory books have left you feeling bewildered & confused, then this book could well be a game changer!

There have, over the years, been many scale books written for bass guitar, and so it is impressive that Alex Lofoco with his instructional book Scale Colour System has been able to deliver a fresh take on the topic. The introductory chapter on scales provides a succinct and insightful exposition of the levels of symmetry inherent in music theory pertaining to the major scale and, in the following and subsequent chapters, its practical application to the fretboard.

The system of colour blocks used to denote fingering patterns is a strong visualisation tool that will help students map out the fretboard and develop a holistic sense of the terrain. Moreover, it greatly aids the identification and visualisation of different fingering combinations across the fretboard in different directions. Each colour block represents a simple finger combination and, when combined across the fretboard, creates a far more intuitive and readily discernible map then the usual visually unrelated dots and numbers typical of scale diagrams applied to the fretboard.

In describing the cycle of fifths the author again well elucidates the theoretical symmetry inherent in the major and minor tonalities of the major scale, their intervallic relationship, and again represents this symmetry in an intuitive visual form that facilitates the recognition of fretboard relationships. In describing minor scales the specifics of the melodic and harmonic minor scales are readily accommodated into the visual representations.

There is in depth analysis of all the associated modes, similar analysis of pentatonic and symmetrical scale forms, all presented in a powerful visual form that I am certain will resonate with many. Further volumes for guitar and on a similar approach to arpeggios will, I am sure, provide an equally valuable and insightful addition to the literature.
