Bb Dominant Seventh Suspended Fourth chord (Bb7sus4) on the guitar fretboard

The Bb Dominant Seventh Suspended Fourth chord (Bb7sus4) is made of Bb (the root), Eb (perfect fourth), F (perfect fifth) and Ab (minor seventh). The fretboard shows every one of them across the neck in standard tuning (E A D G B E), and plays them back so you can hear the chord.

This chord takes the dominant seventh and swaps its third for a fourth. That leaves a suspended fourth with a minor seventh on top. On the neck it overlaps with the shapes of its two parents, the suspended fourth and the dominant seventh.
