This old dog has been playing the guitar since he was 10. Recently I made two purchases. One was a new keyboard and the other was a new guitar. (I like to buy a new guitar every 20 years or so.) My greatest area of weakness in playing the guitar has been rhythm and consistency. The keyboard has an auto-accompaniment feature that includes rhythm. By recording the piano with this rhythm track I have a guide when I play the guitar. If I lose the beat or change the number of beats during the transition between verses I get out of step with the keyboard playback. Suddenly, I am learning to stick with the beat and repeat each verse the same way so that others can sing and play along. What a blast!
