Understanding Keys Unlocks Music

Fretboard Toolbox shows how chords, scales, and keys all fit together, so you can see the music theory that matters most!

Music isn’t random chord & scale shapes

So often we’re shown how to play a certain chord, scale or song, but rarely are we taught how music is a logical system of keys that gives us the ability to create and predict music.

  • The keys are made from groups of notes that create scales.

  • Then those scales determine the chords, and the chord shapes, of the key.

Fretboard Toolbox books show how those chords, scales, and keys make sense.

And they let you quickly see those big ideas, all over your instrument!

Unlocking music doesn’t happen all at once.

  • It happens step-by-step, as you start seeing how beautifully, and predictably, all of the pieces connect.

  • Best of all, when you learn to see the connections on one instrument, you understand them on any instrument!

To start discovering the connections, try following the “Toolbox Path”.

Learn lots more about the Toolbox Path on the Start Here page.

The Toolbox Path (overview)

Step 1. Learn the Major scale and the notes that make up that key.

Step 3. Learn the notes that make each chord, and find them on your instrument.

Step 2. See how the chords are built from those notes.

Step 4. Hear how those chords work together in already familiar ways.

Step 6. Discover the secrets to bluesy sounds in Major keys.

Step 5. Unlock a new world of sounds with natural minor keys.

Next you put your music on shuffle, and start unlocking music!

The Major scale holds the key to unlock the doors.

That’s what Fretboard Toolboxes help you see —

in any key and on any instrument.
