How can I improve my rhythm?
Use a metronome or better yet, a drum machine when practicing. A drum machine usually has many different styles programmed in the presets and are excellent for practicing your rhythm. Also, try to emulate your favorite guitarist by playing along while listening to their CD. Play with other musicians whenever you can. Try to play with musicians that have more experience than you. When practicing, play at a slow tempo until you feel you can move to a faster tempo. Playing too fast is the most common mistake that student makes. Always practice your exercises slow. Band-in-a-Box by PG Music is software that simulates a background band. It can create any genre of music you desire. I love this program. I use it all the time for teaching and practicing. Also, many instruction books come with CD’s. Be sure to use the CD.
