Chord Naming Quick Reference
For accurate results, write chords the way most guitar charts do: root note first, then the chord quality. For example, C means C major, Cm means C minor, C7 means C dominant 7, and Cmaj7 means C major 7.
Use # for sharps, like F#, and b for flats, like Bb. Suspended chords can be entered as sus2 or sus4, such as Dsus4.

Example progressions: G D Em C, Am F C G, Bb F Gm Eb, Dsus4 D G A.
How to Solo Over a Chord Progression
The simplest way to solo over a chord progression is to find the key first. If most of the chords belong to one key, you can usually use that key's major or minor scale across the whole progression.
For guitar players, pentatonic is often the best starting point. It gives you fewer notes to manage and usually sounds musical faster than running a full seven-note scale.
The next level is targeting chord tones. That means when the chord changes, you aim for notes inside the chord instead of just wandering through a scale.
Why One Scale Can Work Over Multiple Chords
Many common progressions are built from chords that all come from the same parent scale. For example, G, D, Em, and C all fit naturally inside G major.
That means a G major scale can work across the whole progression. But if you want the solo to sound intentional, emphasize the notes of each chord as it passes by.
This tool gives you both: the broad scale choice and the chord tone targets that make your phrases lock into the music.
