Music is a beautiful language, but like any language, it relies on clear communication. Just like people speaking the same language can do so with different accents to their voice so too can musicians play the same note but with slight changes in the way it sounds. The pitch may be a bit high or a bit low, and over the centuries musicians have come up with ways to analyze these differences so that multiple musicians can better "play in tune." Just as proper grammar and pronunciation are essential for understanding spoken words, playing in tune is paramount for creating harmonious music. This is where the tuner comes in. For the beginner (or even the more advanced musician) it can be a vital tool for developing accuracy of pitch.
