TABLE OF CHORD FORMULAE

 This is a standard table similar to those found in many guitar 
method books, or chord books. This list is short but has some advanced
concepts and chords. It is not complete, but still has all the most
important chord types. You must understand that some chords can be
described in a number of different ways.(the technical term is 'Enharmonic')



	'Triads'	
 major =            1  3  5 
 minor (m) =        1 b3  5 
 diminished (dim) = 1 b3 b5
 augmented (+) =    1  3 #5 



		     'Sevenths'
	 major (maj7) =            1  3  5   7  
	 minor (m7) =              1 b3  5  b7 
	 dominant (7) =            1  3  5  b7
	"half diminished" (m7b5) = 1 b3 b5  b7 
	 diminished (dim or °) =   1 b3 b5 bb7 (bb7=6 "enharmonic")



			  'Ninth','Altered 7th' and 'Sus7'
		dominant ninth (9) =            1  3  5  b7  9
		seventh sus (7sus) =	        1  4  5  b7	
		seventh flat five (7b5) =       1  3 b5  b7
		flat nine (7b9) =               1  3  5  b7  b9
		seventh augmented (+7 or 7#5) = 1  3 #5  b7  
		sharp nine =			1  3  5  b7  #9	





	'Sixth' chords are not shown, as it's important to 
	understand enharmonic equivalents. A major sixth is enharmonic
	to a minor seventh chord with root a minor third lower
	or a major sixth higher ie G6 = Em7, C6 = Am7, F6 = Dm7, Bb6 = Gm7
	A minor sixth is enharmonic to a minor seven flat five
        with root a minor third lower or a major sixth higher 
	ie. a Gm6 is enharmonic to a Em7b5, Cm6 = Am7b5, F6 = Dm7b5
