A♯sus2 Chord: Guitar, Piano and Notes
The A♯sus2 chord is a suspended second chord built on the root note A♯. Its notes are A♯, B♯ and E♯. It's enharmonically the same chord as B♭sus2.
Suspended second chords sound open and airy. Replacing the third with a second removes the major/minor colour and leaves a hollow, modern feel used heavily in folk, indie and cinematic music.

On the keyboard A♯ is a black key and B♯ and E♯ are white, the keys you'd normally call C and F. The thumb starts on a black key, so slide the whole hand a little further in, towards the fallboard. Practice moving in and out of the chord slowly, then bring in a metronome.

How to use the A♯sus2 chord
The A♯sus2 chord is built from a root, a major second and a perfect fifth. Start at the root A♯ and stack the intervals to get the whole chord: A♯, B♯ and E♯. The same formula gives you the chord in any other key.
Suspended second chords are a signature sound of modern pop, worship music, ambient and post-rock. They're commonly used as colour over a root chord or as an open alternative to major.
How A♯sus2 differs from similar chords
A♯sus2 replaces the third with a major second, so unlike A♯ or A♯m it is neither major nor minor. It is not A♯add9, which keeps the third and adds the ninth on top. Its three notes are the same as those of the sus4 chord built on its fifth.
