Notes and Arpeggios

Diminished triads combine a minor 3rd and a diminished 5th (♭3 and ♭5), creating a tense, unstable sound that naturally wants to resolve. They're most often used as passing chords or chromatic connectors between more stable harmonies. The chord tones are: Db, Fb, Abb. It's built from degrees 1, b3, and b5.

How to Use It

You'll use this sound in everything from basic pop progressions to rock rhythm parts. On bass, you usually outline this chord instead of strumming it: emphasize the root, 3rd, 5th, and 7th as the harmony requires, then use passing tones to connect back to the groove.

Play root and 5th on strong beats, then add the 3rd or 7th to make the chord quality clear. Use the highlights to spot where the same tone repeats across strings.
