The Tools
Scale Explorer
Pick a root and a scale type. See the notes, the interval pattern, and hear the scale played at any tempo — ascending and descending. Eleven scale types across all 12 roots.
C Major
The major scale (Ionian). Bright, foundational.
How to use the explorer
Click a root note (top row) and a scale type (the longer row). The notes appear with their interval labels (the “1” on the left is the root, “3” is the third, etc.). Hit play to hear the scale ascend and then descend — adjust the BPM to slow it down for practice or speed it up for ear training.
Use the explorer for:
- Practicing scale fingerings at a steady tempo (the metronome inside this tool keeps you honest)
- Hearing how a scale type sounds across different keys (D Dorian vs A Dorian)
- Comparing parallel scales (C major vs C minor — same root, different intervals)
- Visualizing intervals: every “♭3” you see means a minor third above the root

FAQ
Common questions.
Why do scales matter?
Every chord, melody, and improvisation in Western music is built from the notes of some scale. Knowing scales lets you compose, improvise, and harmonize without guessing.
What's the difference between a major and minor scale?
The third interval. Major scales have a major 3rd (4 semitones above the root); minor scales have a minor 3rd (3 semitones above the root). That single note shift changes the scale's emotional character from bright to dark.
What are modes?
Modes are scales derived from the major scale by starting on different degrees. Dorian starts on the 2nd degree (so D Dorian = D-E-F-G-A-B-C, the white keys starting from D). Each mode has a distinct flavor: Dorian is jazzy, Phrygian is Spanish-flavored, Lydian is dreamy, Mixolydian is bluesy.
Should I memorize scales by note names or intervals?
Both, but intervals are more transferable. Once you know that a major scale is intervals 1-2-3-4-5-6-7 (whole-whole-half-whole-whole-whole-half), you can play it from any root. Note names anchor the scale to a specific key.
What's the pentatonic scale used for?
Improvisation and pop. The major pentatonic (1-2-3-5-6) skips the half steps, which makes it nearly impossible to play 'wrong' notes over a major chord. Rock and blues guitarists live in the minor pentatonic.
