Hello,
I noticed that a few chord names of the chord name chart in the notation
reference (chapter A.1) are incorrect.
These definitions are apparently derived from "Klaus Ignatzek: Die Jazzmethode für
Klavier 1. Schott, 1995". I have this book in front of me and some chord names are
not correct. Please compare the chord names there on page 18.
1) For example "c - e - g - d" is called "C add9" and not "C 9". Only if the 7 is included, you
call it "C 7/9" or "C 9".
2) The same applies here: "c - e flat - g - f". The correct notation would be "Cm add11" or "Cm
add4". "Cm 11" would be: "c - e flat - g - b flat - d - f" with 7 and 9.
3) "C lyd" and "C maj7 #11" mean the same thing, by the way. "c - e - g - b - f sharp" is
appropriately called "Cmaj7 add#11".
I know that there are different spellings for many chord symbols, but these
mentioned points have actually been adopted incorrectly. I am not aware of any
literature that justifies previous spellings.
