Averaging the highest at 3.17 for the learning aspect, the lowest average in the aspects of software engineering and averaging 3.08 to 3.12 as many aspects of visual communication. Seen that these three aspects have been addressed with a "good" (score 3) which means that Guitar Player application can be run well so you can help the musicians and non-musicians in a practical way to learn guitar.
