Guitar Lick Lab v2.0
Brought to you by Music With Marky
Pick a key and see diatonic triads, 7th chords, common jazz extensions, roman numerals, common progressions, and the relative major or minor — all in one place. Use it to write progressions, harmonize melodies, or just learn the harmonic language of any key.
Chords in a key are built by stacking notes inside the scale. In a major key, the triad pattern is major, minor, minor, major, major, minor, diminished — giving you I, ii, iii, IV, V, vi, and vii°.
Learn this pattern once and you instantly know the chords in every major key.
Roman numerals describe each chord's function in the key, not just its name. A ii-V-I in C major is Dm7-G7-Cmaj7. In G major it becomes Am7-D7-Gmaj7 — same function, different chords.
Thinking in numerals lets you transpose ideas across any key instantly.
Adding a 7th on top of each triad gives you the diatonic 7th chords — especially useful for jazz, blues, funk, soul, R&B, and more colorful rock harmony.
If you want to drill the actual chord tones, the Arpeggio Finder shows every position across the fretboard.
Once you know the chords in a key, you can write a progression and figure out what to solo with. Use the Chord Progression Scale Finder to analyze any progression, or the Scale Over Chord Finder for chord-by-chord scale choices.
