Guitar Scale Finder

The scale you solo or write a melody in should match the key and feel of the backing chords. If the song is in C Major and you want a happy, resolved feel, use the C Major scale. If you want a bluesy edge over the same chords, use the C Major Pentatonic or even the C Blues scale. If the song is in C Minor and you want sad and introspective, use C Natural Minor; for an exotic, dramatic feel, try C Harmonic Minor instead.

The tool shows 14 scales: Major (Ionian), Natural Minor, Pentatonic Major, Pentatonic Minor, Blues, Harmonic Minor, Melodic Minor, the four common modes (Dorian, Mixolydian, Phrygian, Lydian, Locrian), Whole Tone and Chromatic. Each scale shows which notes are in it, the formula in whole steps and half steps (W = whole step, H = half step, 1.5 = step and a half), and the chords that come from that scale.

Pentatonic scales have 5 notes; diatonic scales (major and minor) have 7. The pentatonic scales remove the two notes that can clash with the underlying chords (the 4th and 7th in major; the 2nd and 6th in minor). This makes pentatonic almost foolproof: any note you play over a backing track will sound good. That is why beginner blues and rock soloists are taught the minor pentatonic first; you can shred badly and still sound musical.

Diatonic scales sound richer and more varied but require more thought. The 4th and 7th create tension that you need to resolve quickly to a stable note (1, 3 or 5). Most professional soloists weave between pentatonic and diatonic; pentatonic for the safe, repeated motifs, diatonic for the moments where the melody pushes against the harmony. The [chord library](/chord-library) shows which chord notes correspond to which scale degrees.

A mode is a major scale played from a different starting note. The C Major scale (C-D-E-F-G-A-B) becomes D Dorian if you start on D and treat D as home. It becomes E Phrygian if you start on E. Same notes, different feel, because the relationships to home note change. Dorian (start on the 2nd) feels jazzy minor. Mixolydian (start on the 5th) feels bluesy. Phrygian (start on the 3rd) feels Spanish or exotic. Lydian (start on the 4th) feels dreamy and bright.

Modes are why two songs in the 'same notes' can feel completely different. The minor blues scale and the Dorian mode both have a dark colour but they hit you differently. The classic example: So What by Miles Davis sits on D Dorian for half its length, then jumps up to Eb Dorian. Same scale shape, transposed. Once your ear knows what each mode sounds like, you can pick the one that fits the mood you want without thinking about theory.

The fretboard view shows where every note of the scale sits on a standard-tuned 6-string guitar across 15 frets. The root notes are highlighted so you always know where to start patterns. Click any string to hear that note played, or hit the play button to hear the whole scale ascend and descend. The display mode toggle switches between note names (C, D, E) and interval numbers (1, 2, 3) so you can train your eye to see relationships rather than just memorise positions.

The smart way to use this is to learn one position at a time. The minor pentatonic 'box 1' shape (root on the 6th string) covers about 4 frets and is the foundation of 90% of rock and blues lead playing. Master that single shape in every key by sliding it up and down the neck. Then learn box 2, which sits a bit higher up. After 5 boxes you have the entire neck mapped. The [music theory reference](/music-theory) puts these shapes into the wider context of keys and modes.
