Whether you play rock, jazz, classical music or any other style, its always important to be in tune. You may be able to fly around the guitar,

or sax, and you may have mastered many impressive techniques, but if your instrument is not well tuned, the result will still sound painful!
Electronic tuners are small, normally hand-held devices which generally fall into one of two

TemperamentThe adjustment of the intervals between notes in various tuning systems. All tuning systems involve some degree of compromise as by definition, not all intervals can be mathematically pure within the same system. Many different temperaments exist both in theory and practice; by far the most common in modern music is 'equal temperament', which divides the octave exactly into twelve, so that the ratio of frequencies between two notes a semitone apart is one to the twelfth root of two.temperament
