B Mixolydian Mode

What is the B Mixolydian Mode?

Mixolydian is the fifth mode of the major scale, and its ♭7 gives it a sound that sits right between major and blues — bright but with a groove. It's the secret ingredient in classic rock rhythm parts, Grateful Dead jams, and any major-key riff that wants to feel relaxed rather than resolved. Here's how the B Mixolydian Mode lays out on the fretboard.

Notes and Positions

The fifth mode - major with a flat 7th. Dominant and bluesy. On bass, the fretboard view helps you visualize where the important tones sit for building lines across positions. Use a finger-per-fret approach first, then add shifts only when the line needs a wider range. In the key of B, the notes are: B, C#, D#, E, F#, G#, A.

How to Use It

You'll often hear it in Rock, Blues, Country, and Jam Bands. A good way to internalize the sound is to sing the root, then sing a few scale degrees before you play them.

Practice root-on-E and root-on-A boxes separately, then connect them with one clean position shift. Use the interactive fretboard above to spot repeats of the same note on different strings and frets.
