The easiest way of tuning your guitar is to use an electronic guitar tuner – basic models are available for under £10.
A particular feature that is useful for beginners is an off-note indication. This will tell you which way to tune even if the string is a very long way out of tune.
Beginners generally don't need 'chromatic' tuners, or ones with adjustable pitch.
Automatic note selection makes the tuner easy to use if the strings are roughly in tune, but can confuse beginners if the guitar is a long way out of tune or if the strings have just been replaced. A simple non-chromatic tuner with a clear display and a choice of both automatic and manual modes is ideal for beginners and those with LED displays are ideal.
If you are beginner playing acoustic guitar only (whether steel strung or classical nylon strung), you could also consider a clip-on tuner. This type of tuner picks up sound vibrations directly via the head of the guitar instead of through a microphone.
