Why visualize scales on the fretboard

See the whole neck

Spot where scale notes repeat so you can move freely between positions.

Learn intervals, not shapes

Interval labels show what each note does, which makes improvising easier.

Any tuning, any instrument

Explore drop and open tunings, 7-string guitar, bass and ukulele.

How to use the fretboard visualizer

  1. Pick root and scaleChoose a root note and one of 15 scales or modes.
  2. Set your instrumentSelect a tuning, the number of frets and left- or right-handed view.
  3. Explore and listenSwitch labels, highlight a fret range to focus on one position and click notes to hear them.

How the fretboard map is drawn

For every string, the open note from the chosen tuning is raised one semitone per fret. A note is shown when its distance from the root, ignoring octaves, is part of the scale formula. Root notes are orange so you can anchor each position, and the highest string is drawn on top, as in tab.

Intervals are labeled relative to the root, such as b3 for a minor third and b7 for a minor seventh. Scale degrees number each note in order from 1. Use the highlight range to dim everything outside a block of frets and learn the scale one position at a time.

Minor pentatonic

Five notes that work over most rock and blues, the usual first scale to learn.

Modes

Dorian, Mixolydian and the others are the major scale started from a different degree.

Blues scale

Minor pentatonic plus the b5 blue note.

Guitar scale fretboard FAQ

Why is the top line the high E string?

The diagram follows tab orientation, where the thinnest string is on top and the thickest on the bottom.

What do the orange dots mean?

They mark the root note of the scale, the note the scale is named after.

How do I learn one position at a time?

Set the highlight range to a block of four or five frets, such as 5 to 8. Notes outside the range fade out.

Can I use it for bass or ukulele?

Yes. Choose a bass or ukulele tuning from the list. The ukulele tuning is re-entrant, with a high G string.

Why are some notes written with flats?

Auto spelling uses flats in keys that are normally written with flats, such as F or Bb. You can force sharps or flats.
