F#6 and D#m7
F#6 has exactly the same notes as D#m7. Put F# in the bass and it sounds like a major chord with a sweet 6th; put D# in the bass and it is a minor seventh.
Building F#6 from F#
Formula 1 3 5 6. Count from F# and every number is a step of the F# major scale, and a b lowers it by one key.
Start chord: F#
| Note | Step | Interval | Keys from F# |
|---|---|---|---|
| F# | 1 | root | 0 |
| A# | 3 | major 3rd | 4 |
| C# | 5 | perfect 5th | 7 |
| D# | 6 | major 6th | 9 |
F#6 in every position
Same notes, different order. Pick the position closest to the chord you just played.
Root position: F# A# C# D#
1st inversion: A# C# D# F#
2nd inversion: C# D# F# A#
3rd inversion: D# F# A# C#
Hands and fingers
| Right hand | F# A# C# D# | 1 2 3 5 |
|---|---|---|
| Left hand | F# A# C# D# | 5 3 2 1 |
Practise F#6 in four steps
- Find F#, then add the other notes one at a time: F#, A#, C# and D#.
- Play F#, then F#6, then F# again, and hear what the added 6th brings to the chord.
- Try F#6 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.
Come back to F#6 tomorrow: short daily sessions beat one long one.
Where F#6 is used
- F#6 is a home chord: it replaces F# at the end of a song in F# major.
- It is also the IV chord in C# major, a soft colour before going home.
