Chords 13, 11.

[Lineinput]

Hi there, I'm trying to follow the tutorial about chord recognition, but sometimes in some scores I read, I can see chords like 13 or 11, I can't find them in the exercises in Earmaster, I know the program is mainly for EAR training, but woul be great if we have some information about how to build chords.
I'm very happy with Earmaster, I just want to make this comments to make this program better.

I also propose the score reading trainer, one utility useful to improve the way we read scores, that'd be awesome.

There is lots of material on how to build chords, a good text book can be Mark Levine's "The Jazz Theory Book". Some mentions this books as "The jazz bible". It's in english, and often a good read.
