How to determine which (slash) chord to use?
I usually notice the patterns of making chord progressions with defining its root notes. These root notes actually the main notes that I will sing in and from there I can decide to use which chords can be used to accompany my singing. Sometimes it is not a difficult thing because I can find the chords I need by simply using barre chords, but most other times it is not that simple. There are times when I am stuck with no exact chord because I can't find it in major/minor and left me clueless when it comes to slash chords or diminished and all sort of things. So which is the best way to determine the chords I have to use? Especially with slash chords or 7th and other formations beside major and minor.
