It is important to tune a nylon guitar properly. If you are concerned that you can’t find an affordable guitar it is possible to find cheap electric guitars online that are very good quality. It is necessary to retune your guitar on a regular basis. Cold, heat, dry or moist conditions and even just playing the guitar will cause a guitar to go out of tune. Strings need to be replaced regularly; at least every 4 to 6 months. An electric guitar tuner can help immensely with this process. They are relatively inexpensive to buy and very easy to use! When using the guitar tuner play the bottom string of the guitar as a light (for the first or E string) will flash on the guitar tuner. Normally three lights flash for the E string giving you feedback on how the string is tuned. Therefore the one light on the left will flash if the string sounds flat (sound or pitch of the string is too low), the middle light will flash if the sound is “just right” and the other light on the right will flash if the sound is too sharp (sound or pitch of the string is too high).
The tuner may be designed with a needle that moves instead of lights. Use this in the same way as described earlier. The indicator will move down to the left if the string is too low and to the middle or top if it is “just right” (perfect sound and pitch) and then on and down to right where it is pitched too high. There are many different models and types of electronic guitar tuners being sold on the market and so it is difficult to describe how each works.
