When using moveable chord shapes, it is important to be able to quickly find the correct fret at which to play each chord and also to be able to play equally well in all keys. The best way to achieve this is to memorize the names of all the notes on the fretboard. This may seem a daunting task, but it can be done and will be well worth it. More advanced guitar playing requires the use of many different scales, chords and arpeggios, which may take their name from any of the six strings, so you need to learn them all equally well.
