F-sharp dominant 7th chord

How to play F♯7 on piano

The F♯7 chord is F♯ A♯ C♯ E: F♯ (root), A♯ (major 3rd), C♯ (perfect 5th), E (minor 7th).

Spread four fingers over the four notes, thumb on F♯ in the right hand and the little finger on F♯ in the left.

Each inversion moves the bottom note up an octave. Practicing them in a row teaches your hand the same chord in three or four shapes, so you can reach it from wherever your hand already is.
