F#m9 and Amaj7
The four upper notes of F#m9, A C# E G#, are Amaj7. Play F# low and Amaj7 above it: that is the whole F#m9, and a quick way to reach it.
Building F#m9 from F#m7
Start from F#m7, which you may already know, and change one thing: add G# above the minor seventh.
Start chord: F#m7
| Note | Step | Interval | Keys from F# |
|---|---|---|---|
| F# | 1 | root | 0 |
| A | b3 | minor 3rd | 3 |
| C# | 5 | perfect 5th | 7 |
| E | b7 | minor 7th | 10 |
| G# | 9 | major 9th | 14 |
A short F#m9 routine
- Say the notes out loud while you press them: F#, A, C#, E and G#.
- Switch between F#m7 and F#m9 ten times without looking at your hand.
- Alternate root position and a rootless shape with the 3rd on the bottom, keeping shared notes still.
- Then test it in random order among other chords: recall under time pressure is what sticks.
Keep each session short and frequent and F#m9 will become automatic.
When to play F#m9
- F#m9 is the ii chord of E major and the vi chord of A major.
- In a ii-V-I it often opens the line: F#m9 → B7 → Emaj7.
