This next little trick is again about playing in the key of B without barre chords or a capo but this time uses all the open strings and gives you some great new voicings simply by detuning the top E (string 1) down 1 semitone or a ½ step to D#. This ingenious idea (that I didn’t invent myself btw) turns that dissonant top E into a 3rd and sounds infinitely prettier.
You’ll have to use some slightly different shapes to the ones I showed you for B but nothing too arduous. Coldplay used this trick on their breakout hit ‘Yellow’ and it sounds great if applied to the right worship song. Realistically you might want to have a spare or borrowed guitar already retuned this way if you can’t tune quickly, accurately and silently on the fly.
