Progressions to try

Which shape should you use?

On guitar, start with x13311, a barre at the 1st fret. Press the barred notes evenly and mute any strings marked x. The x-x-8-10-11-8 shape gives you another position when the neighboring chords sit elsewhere on the neck.

On ukulele, the open shape 3011 is the easiest place to start. The 3563 grip moves the chord to another register.

On piano, play B flat-C-F. Move B flat up an octave to reach the first inversion, C-F-B flat; the notes remain the same while the lowest voice changes.

What are the inversions?

B flat is the root, C the second and F the fifth. There is no third in this chord.

  • Root position: B flat-C-F, with B flat lowest.
  • First inversion: C-F-B flat, written Bbsus2/C if C is lowest in the whole arrangement.
  • Second inversion: F-B flat-C, written Bbsus2/F if F is lowest in the whole arrangement.

A slash chord names the note in the bass, not merely the lowest note under one hand. Chord Inversions shows how to read that distinction.

How does Bbsus2 differ from Bb?

Keep B flat and F; replace the second, C, with the major third, D, to make Bb. A sus2 chord does not keep the third alongside the second. Try that one-note change on piano, then use the comparer to hear it in the full chord. See Bb for the other chord's full spelling and roles.
