Piano Diagram of Bbsus2 in Root Position
The Bbsus2 chord consists of three notes: Bb, C, and F. This chord is known as a suspended second chord, where the third note of the chord is replaced by a major second. To play the Bbsus2 chord on a piano, simply replace the third note of a Bb major chord (D) with the major second (C). Keep reading to get a better grip on the music theory behind this chord.

Bbsus2 Chord Inversions
The Bbsus2 chord has a total of 2 inversions:
Root Position: | Bb | C | F |
1st Inversion: | C | F | Bb |
2nd Inversion: | F | Bb | C |

Bbsus2 Chord Equivalencies
An interesting detail about sus2 chords is that their 2nd inversion results in a sus4 chord. To clarify, when the 5th note of a sus2 chord becomes the root note, it transforms into a sus4 chord.
2nd Inversion of Bbsus2 = Fsus4
For instance, if we take the Bbsus2 chord with the notes Bb, C, and F and rearrange them so that F becomes the root note, we end up with an Fsus4 chord with the notes F, Bb, and C. Therefore, the 2nd inversion of Bbsus2 is equivalent to Fsus4.
Music Theory and Harmony of Bbsus2
What are Suspended Chords?
In suspended chords, the third note is replaced by either a major second or a perfect fourth. The resulting chords are called suspended second (sus2) or suspended fourth (sus4) chords, respectively. These chords create a unique and sometimes unresolved sound that can add tension and interest to a musical composition.
Suspended chords have a distinctive sound that sets them apart from major and minor chords. They are so-called because they temporarily suspend the listener’s expectation of hearing a major or minor stable chord. Instead, they feature a perfect fourth or major second interval in place of the third. Due to their “neutral nature”, suspended chords can sometimes be used as substitutes for both, major and minor chords.
Building the Bbsus2 Chord: Different Approaches
Starting from the Bb major Scale
To build a sus2 chord, you can use the major scale as a guide and combine a root note, a major 2nd interval, and a perfect 5th interval. For example, to form a Bbsus2 chord, you can begin with the Bb major scale, which includes the notes Bb, C, D, Eb, F, G, and A.

Keyless notation of Bb Major scale.
To create a Bbsus2 chord, apply the formula R, 2, 5 in the following manner:
- Begin with the Root note, which is Bb.
- Select the major 2nd interval, which is C, and add it to the chord.
- Finally, add the 5th interval, which is F.
By following this simple formula, you can create a sus2 chord from any major scale.
by Combining Intervals
One method to create a suspended 2nd chord is by combining two specific intervals – a major 2nd, and a perfect 4th.
2 + 4 = sus2 Chords
To illustrate, let’s use the Bbsus2 chord as an example. By examining the intervals between the notes, we can see that Bb-C forms a major 2nd interval (a whole tone), and C-F creates a perfect 4th interval.
How to Use Bbsus2 in a Chord Progression
Suspended second (sus2) chords are neither major nor minor, making them a great option to create tension and suspense before resolving to major and minor chords.
The tables below show the harmonization of major and relative natural minor scales for keys that include Bb major (including Bb7 chords) and Bb minor chords in various positions and different harmonic roles.

Bbsus2 Chord Function in Major and Minor Keys
Understanding Scale Degrees
When creating chords from a scale, each note in the scale is assigned a degree, which reflects its position in the scale. In the diatonic major scale, there are seven degrees, and each degree has a unique role in the overall harmony of the scale.
- The first degree of the scale is called the Tonic, and it serves as the foundation for the scale. It provides a stable tonal center and is often referred to as the “home base” of the music.
- The second degree of the scale is called the Supertonic. It’s typically used as a passing note between the tonic and other scale degrees, and it adds a sense of movement to the melody or harmony.
- The third degree of the scale is called the Mediant. It’s located halfway between the tonic and dominant notes and helps to establish whether the scale is major or minor.
- The fourth degree of the scale is called the Subdominant. It’s often used as a complementary harmony to the dominant and adds a sense of tension and resolution to the music.
- The fifth degree of the scale is called the Dominant. It generates tension and a sense of expectation, and it’s typically resolved by returning to the tonic.
- The sixth degree of the scale is called the Submediant. It’s often utilized as a transition between the dominant and tonic, and it provides a sense of stability and restfulness to the music.
- The seventh degree of the scale is called the Leading tone. It’s located one half step below the tonic and produces a strong sense of tension and a desire to resolve to the tonic. It’s often used to create a sense of resolution and finality in the melody or harmony.
Bbsus2 in Bb Major
The Bbsus2 chord can be used along with the Bb Maj7 chord (or any other kind of Bb major chord) on the first degree to create movement in a chord progression. The Bbsus2 chord can suspend the Bb Major chord or the subsequent chord.

Conclusion
While the chord progressions and examples in this post offer a comprehensive overview of common uses for the Bbsus2 chord, space constraints prevent a full exploration of advanced harmony topics. These include chord progressions based on scales, modal interchange, and jazz harmony. However, readers are encouraged to continue their studies to gain a deeper understanding of the harmonic possibilities beyond the basics presented here.
