How to read this arpeggio

The chord tones are shown as pitch classes first. In the fretboard tool, square markers represent Bb root notes, while circular markers represent the remaining tones in the arpeggio.

Use the interactive fretboard to locate the Bb root notes and connect the remaining sus4 chord tones across standard tuning.

This same arpeggio shape is also commonly called Bb Suspended 4 or Bb Suspended Fourth.

Chord construction and defining tones

4Eb
5F

Bb sus4 combines 4 (Eb) and 5 (F). The fourth replaces the third and creates a suspended sound with a close move available to the major third.

Harmonic use

Use this arpeggio over Bbsus4 or to create a suspension that resolves when the fourth falls to the third.

Practice this arpeggio on guitar

  1. Play the Bb Sus4 arpeggio from one Bb root to the next in at least two fretboard positions, saying each note name and interval degree aloud.
  2. Play 4 (Eb) and 5 (F) in small groups and hear the tension between the fourth and fifth.
  3. Outline Bbsus4, then resolve the fourth down by one fret when the underlying chord changes to major.
