F#/A# — with the third in the bass (first inversion)
Also written Gb/Bb — the same chord, spelled the other way.
Notes in F#/A#: A# – F# – C#Formula: 1 – 3 – 5 / 3In the formula, the numbers count steps of the major scale starting from the note that names the chord; "b" lowers a half step, "#" raises one — and a slash names the bass note.
C/E is the C major chord with E in the bass — the first inversion. The harmony is the same, but the bass becomes lighter and gains melodic direction.
The same chord on all four instruments
Where to use it: Melodic bass lines and smooth transitions between chords.
