Watch the Day 1 online guitar lesson by Ravi from Learn Guitar in 21 Days

One of the biggest contributors to frustration in learning guitar is dealing with an instrument that is out of tune. No matter how much you know or how hard you practice, you won't enjoy the sound if your guitar is out of tune.

While it is a good idea to learn to recognize pitch and to be able to bring the guitar into tune by ear, this is something that will develop naturally as you continue to play. So, in the interest of getting you up and running quickly, get yourself an electronic tuner and begin each day's lesson by tuning up.

Even the most experienced guitar players rely on electronic tuners, as they are fast, accurate, and easy! Listen to the sound of the guitar while you follow the tuner's lights and/or needle to bring the guitar into correct pitch, and you will begin to hear the subtle as well as obvious difference between being in and out of tune.
