What's a 7#9 chord?
A 7#9 chord is a dominant 7th chord (1 - 3 - 5 - b7) with a ninth raised by a semitone (#9) giving the formula 1 - 3 - 5 - b7 - #9.
How to build 7#9 chords?

|Dominant seventh chord||1||3||5||b7|
|Dominant 9th chord||1||3||5||b7||9|
|Dominant 7#9 chord||1||3||5||b7||#9 (b3)|
7#9 chords have a blues sound because of the major third and the minor third. Indeed, as you can see in the chart above, the #9 can be considered as the minor third (b3). This type of chord is often referred as the Hendrix (Jimmy) chord because of its use in Purple haze.
There is much of it in many jazz-blues compositions and very used by hard-bop musicians as Wes Montgomery (Four on six, Full House, D natural blues), Kenny Burrell (Chitlins con carne), Grant Green, Lou Donaldson and many more.
Dominant 7#9 chords can be written 7+9 or 7#9.
