To make an “F sharp seventh” (F#7) or “G
flat seventh” (Gb7) chord we use
the 1st note F#
the 3rd note A#
the 5th note C#
the b7th (half step lower
from the 7th) note E
This gives us the notes F#, A#, C# and E
which form the
“F sharp seventh” or “G flat seventh”
chord
“F sharp seventh” (F#7)
or
“G flat seventh” (Gb7) on the guitar
“F sharp seventh” (F#7)
or
“G flat seventh” (Gb7) on the piano
