An in tune guitar is essential for every guitarist. Having an in tune guitar helps you to identify when your chords and fingering are correct as well as develop your ear in recognising how chords sound and how notes relate to each other. If your guitar isn’t in tune when you do the majority of your practice you're missing out on some key benefits as a growing musician and as the market is flooded with so many tuners for all types of instruments it's hard to decide which one is best for you. On my page Best Guitar Tuners I recommend a few different types of great guitar tuners which I believe are great for any guitarist, wether they’re just beginning or more advanced, and to suit a few different scenarios. If you’re looking for an online guitar tuner, their are various options of which are outlined in my Online Tuners page. If you’re looking for a guitar tuner on your phone or device I highly recommend Cleartune, you may have to fork out a few bucks but it is by far the most accurate chromatic tuner I have experienced.
