The construction rules F♯7♭5 follows
Start from a triad
Root, 3rd and 5th, stacked in thirds. The 3rd makes it major or minor; the 5th makes it diminished or augmented when it moves.
A third on top makes a 7th chord
A major 7th over a major triad is maj7, a ♭7 is a dominant 7. Over minor you get m7 or m(maj7); over diminished, m7♭5 or the °7, whose 7th is lowered twice.
On guitar, something has to give
Each extension takes the string of a triad note that matters less, usually the 5th, or gets a string of its own. The root and 3rd stay: they say what the chord is.
The root can move down
When an extension needs the root’s string, the root can drop to the string below the triad: an anchored voicing keeps the bass and frees a string on top.
Alter a dominant for tension
Raise or lower the 5th or the 9th, or add a ♯11 or ♭13, and a dominant 7th pulls harder towards the next chord: G7♯9, G7♭9, G7♭13.
All the rules, with examples, in the guide to the chord library.
