You know all the basic types of chords – major chords, minor chords, 7th chords and so on. But did you know that any chord can be altered just by adding a “+” sign or a “-” sign?
If a plus sign “+” is added to a chord like this: C7+5 it means to raise the 5th one-half step. If a minus sign “-” is added to a chord such as C7 it would look like this: C7-5 and means to lower the 5th one-half step.
