Key and chord chart
A chart with keys and chords shows the relationship of chords in all the keys. From left to right you can see a key and the chords that belong to it. If you are looking for an overview of guitar chords, see the chart.
Chart with chords sorted by key
The chord chart above is very useful because it tells you which chords that belongs to a certain key. As soon you know this you also know which chords that are well played together.
Let’s look at the chord chart and the column that begins with C. Here we find C, Dm, Em, F, G and Am. Every one of these chords will always sound nice mix together. Try the following chord progression:
C - Em - Am - F - G - C
Really nice and smooth isn’t it? Of course, sometimes we want some dissonance in our music but the chart above gives us the fundamentals for making chord progressions.
This also helps us to write our own songs because, by the chart, we recognize chords that working together and it also gives guidelines how to change key in a song, for example, when going from verse to chorus.
