|---|---|---|---|
| F# | 1 | root | 0 |
| G# | 2 | major 2nd | 2 |
| C# | 5 | perfect 5th | 7 |

Keys and moves for F#sus2
- F#sus2 works in the keys where F# already lives: F# major, C# major and B major.
- It often comes back to F# or slides to F#m, because without a third it can lean either way.
Make F#sus2 automatic
- Find F#, then add the other notes one at a time: F#, G# and C#.
- Switch between F# and F#sus2 ten times without looking at your hand.
- Alternate root position and 1st inversion, keeping shared notes still.
- Last, meet F#sus2 mixed with chords you already know, in an order you did not plan.
Keep each session short and frequent and F#sus2 will become automatic.
