Help Reading Chord Charts

[terenceob]

Hello,

I just bought iGigBook and I love it, but have a question about the transposable chord charts that I cannot seem to find an answer to. Some of the Chord charts have different chords in a greyed out type face above some of the "main" chords. IE, above an FMaj7 there is a Dmin7. Are they alternates, or maybe differences in repeats?

In addition to this, there are other several notations that I was not familiar with that I found answers to (major 7ths using a triangle for instance) Is there a place I could go to to see a list or legend of all the notation symbols used in these chord charts in one place?

The greyed out chords are alternate chords which can be played in lieu of the chord it's on top of. I don't know if there's a legend that covers everything that you might see on a chord chart. Different people use different ways to express the same thing, for example:

A C Major chord could be expressed as:

C
CMaj
CΔ
CM (as opposed to Cm which would be C minor)
