Guitar performance, create two different guitar parts: a rhythm guitar strings (using a lower pitch) and a main guitar phrase (using most high pitch). Now, don't worry about making them too complicated. Once you've created two parts, you can combine the two parts together and play them "in time", and there's no sloppy noise/hesitation in switching from one part to the next. For this exercise, it is useful to use the metronome exercise. Also, record your performance so that you can hear any mistakes you make. This makes it easier to find yourself playing the cheap electric guitars in time.
