  1. Can anyone tell me the formula of a 9 Chord?

    ex: F#9.

    I'm thinking Dao wants 1-3-5-b7-9, a "formula" for a Dominant 9th chord.
    So, with F#9 as the example:

    I agree with JimK. The suffix 9 implies a dominant 9th chord. When a ninth chord has no dominant seventh, it needs to be specified i.e. F#maj7-9 or F#6-9. If there are no tensions before the ninth (sixth or seventh), it would be an F#(add 9). :)

    ...or possible F#add2, or if there's no third in it (IE the chord was played F#. C#, G#, voiced in fifths) it might be F#sus2, or rather confusingly, just F#2.

    There's a big problem with the way chords are named - the conventions are largely based on a system that was laid down about 4-500 years ago, and is now well overdue for an overhaul, but sadly, I don't think the billions of musicians in the world using western naming conventions are going to listen to lil' ole me... :oops:)

    As for F#9, it is indeed a dominant 7 chord with a 9 on the top.

    F#Maj7 with a 9 can just be written as F#Maj9 - that's OK.
