You’ll Find:

• The main A5 Sliding Scale sheet.

• Four scale sheets: 

Major, Natural Minor, Melodic Minor and Harmonic Minor

• Two paper clips

1. Choose a scale sheet (e.g. Major Scale).

2. Place it onto the Sliding Scale with your desired key note sitting in the top box.

3. Secure the sheet in place using the paper clips.

• Read the scale notes downwards, following the alphabetical order.

• Each note of the scale is listed, and the key notes are highlighted in bold.

•Important: Do not read any note that breaks the alphabetical sequence.

• For example, if you select A as your key note using the major scale sheet, you’ll get:

A, B, C#, D, E, F#, G# (the notes of the A major scale).

To the right-hand side of the scale, you’ll find a list of chords that match each scale note. In the A major example:

1. A major (or A major 7th)

2. B minor (or B minor 7th)

3. C# minor (or C# minor 7th)

And so on, following the harmony of the scale.

Change Keys with Ease

Changing keys has never been so easy. Simply move the slider to a new root note, and the entire scale, chords, and modes update instantly.

The Sliding Scale works for all keys — A, Bb, B, C, C#/Db, D, Eb, E, F, F#/Gb, G, and G#/Ab — so you can explore any tonal centre in seconds. You can also switch between Major, Natural Minor, Melodic Minor, and Harmonic Minor scales, with every key, chord, and mode adjusting automatically.

Whether you’re writing a song in C major and want to experiment with F# minor, or just chasing a new sound, key changes and scale swaps are now as simple as a single move.

Play the Modes

The Sliding Scale also makes playing modes simple. For instance, with A major, if you shift your focus to B, you’re now in B Dorian. You’ll now have: B, C#, D, E, F#, G#, A

You’d begin with the B minor chord (or  B minor 7th), and follow with other chords from the same set.

Each mode is listed on the right above the correct chord degree.

Switching Scales

You can also switch between Major, Natural Minor, Melodic Minor, and Harmonic Minor scales with a single click — and The Sliding Scale instantly updates every key, mode, and chord to match, giving you a complete view of the new tonal landscape in seconds.

Roman Numerals

You’ll also notice Roman numerals on the scale sheets, which help you quickly identify whether to play a major, minor, diminished, or augmented chord.

Capital Roman numerals = Major

Lowercase Roman numerals = Minor

+ = Augmented

ø = Half-diminished

◦ = Diminished 7th

For example, in the major scale, the I chord is major, the ii chord is minor, and so on.

On the left-hand side of each scale sheet, you’ll also find the interval formula. For example, the major scale is:

W - W - H - W - W - W - H

W = Whole step (two semitones or two frets)

H = Half step (one semitone or one fret)

This is useful for those who want to deepen their understanding of how scales are built.

Every Essential Scale and Chord You Will Ever Need, is the companion book for the sliding scale. It has been created for Piano, Guitar, Bass, Ukulele, Banjo and Mandolin. A unique book that includes every essential open chord, CAGED chord, inversion, note, scale, mode and when to use them (in every key).
