it gets even more complicated when you start using only parts of these barre chords utilising only 3 or 4 strings. The low strings or the high strings. Sometimes as an easier chord to make while you persevere learning full barre chords.

The barre chord chosen will depend on which areas of the fret board the song or melody is utilising.

It means the chosen chords stay closer together and are easier to change between.
