Why You Shouldn't Tune Guitar to a Piano

It may sound like a good idea to tune your guitar, banjo, mandolin, or other string/wind instrument to your in-tune piano. This is because when you get your piano tuned you probably think all the notes are then perfectly in tune, but this isn't quite the case. When the piano is tuned the tuner is tuning the piano so that all the notes sound in tune and the goal is for the octaves(same note just 12 keys apart) to be perfectly in tune. This means that not every note will be perfectly in tune, if that were the case then the piano would sound out of tune. So when you try and tune your guitar or other instrument to a piano, you will be tuning your instrument a little shy of in tune. If you are using the piano so that you can work on tuning your instrument with your ears, instead of just looking at a tuner to see when you're in tune, I would suggest using tuning drones. You can get tuning drones online or look some up on YouTube. Using drones to tune your instruments is a great way to develop your ears and your ability to hear if you are in tune or not, it is also a very useful skill to have when playing with other people.
