There are three card sides with chord diagrams on them. These 18 chords are some of the most common used when playing guitar. Especially when starting out.
The grid for each diagram represents the fret board. Each horizontal line is a string and the vertical lines are frets.
From the bottom horizontal line to the top are the E, A, D, G, B and E strings. So the high E string is at the top of the diagram.
The far left vertical line is fret 0 (AKA an open string) and then frets 1, 2 and 3.
REMOVE?:::::::You will see that some chords have a number underneath their first fret. This is to show that this chord starts on a different fret than 1.
REMOVE?:::::::For example, the chord Cm has a 4 underneath it. So it is played starting on the fourth fret.
On the far left of some chords there are some circles and crosses. The circles mean that you should play that string open. The crosses mean that you should not play that string.
These sides contain every chord in every scale. This is especially helpful for transposing songs from one key to another.
The top row shows the chord number in roman numberals. Starting with I (Or i) which is the root chord to VII° (or vii) which is the seventh.
Some numerals are lowercase, some are uppercase and some have the ° symbol after them. They are written that way to help you remember what type of chord should be played there.
Your band is covering Bon Jovi's It's My Life. The chord progression for the chorus is I V vi IV.
If you were playing the song in the key of C Major, you can use the cards to see that the chords you should play are C, G, Am then F.
If your singer decides that that key if too low for him and wants to change it to D Major. No problem! The cards show you that the new chords are D, A, Bm and G.
Why are the keys not in alphabetical order?
The keys have been ordered in a particular way starting with the key of C Major. This is because C Major is the simplest key to learn as it contains no sharps or flats.
The next key is G Major. this key contains only one sharp. And so on.
The order of keys also represents the Circle of Fifths.
The minor keys card is layed out in the same way starting with A Minor. A Minor is C Major's relative minor key meaning if contains all the same notes as C Major.
Notes on the frets with standard tuning.
Fret 12 is the same as fret 0 and they repeat from there.
