Watch the Changing Duration online guitar lesson by Vicki Genfan from Acoustic Rhythm Survival Guide
You can refer back to our original discussion about changing the duration of your chords in a progression. However, another idea to try is stepping out of the 'even' number of measures... what I mean is this: Try playing your I chord for the first 3 beats of a measure, then switch to the V chord for the last beat.
Next measure the same – start out on the I chord. OR you could try 1 ½ measures of I chord and the last two beats of the second measure switch to the V chord. TRY starting with the V chord, play it for 1 measure and the 1st beat of the next measure. Then go to the I chord for the last 3 beats.
Get my drift here? Be strange, unusual, take chances, do things differently! You'll create some new pathways in your brain, and you'll undoubtedly get your creative juices flowing in new ways!
As I keep saying, PLEASE record your explorations!
As long as you keep the attitude of the 'explorer', you will continue to find the new and unexpected in your playing... I promise!
