The 'b9' signifies a Minor Ninth interval. This means the ninth note of the scale is lowered by a half step from a major ninth, adding a distinctive complex and rich quality to the chord.

How do you build the F# 7(b9) chord using intervals?

You build the F# 7(b9) chord by stacking specific intervals from the root note (F#): a Major Third (A#), a Perfect Fifth (C#), a Minor Seventh (E), and finally a Minor Ninth (G). Understanding these intervals on the fretboard is crucial.
