A second name for the same keys
The notes of F#sus4 also spell Bsus2: start from B and you get root, 2nd and 5th of B. Same keys, two names, and the lowest note picks the one you hear.
The formula of F#sus4
Start from F#, which you may already know, and change one thing: raise the third A# one half step to B.
Start chord: F#
| Note | Step | Interval | Keys from F# |
|---|---|---|---|
| F# | 1 | root | 0 |
| B | 4 | perfect 4th | 5 |
| C# | 5 | perfect 5th | 7 |
Practise F#sus4 in four steps
- Say the notes out loud while you press them: F#, B and C#.
- Play F#, then F#sus4, then F# again, and hear what the 4th pulls back toward the third.
- Try F#sus4 in 1st inversion, the position that sits closest to your last chord.
- Then test it in random order among other chords: recall under time pressure is what sticks.
Five minutes a day is enough to make F#sus4 feel easy.
When to play F#sus4
- The classic move is F#sus4 → F#: the 4th B falls one step to the third A# and the tension melts.
- You can use it in F# major, C# major and B major, wherever F# itself fits.
