context_page_description: In music, an electronic tuner is a device that detects and displays the pitch of musical notes played on a musical instrument. "Pitch" is the highness or lowness of a musical note, which is typically measured in Hertz. Simple tuners indicate—typically with an analog needle-dial, LEDs, or an LCD screen—whether a pitch is lower, higher, or equal to the desired pitch. In the 2010s, software applications can turn a smartphone, tablet, or personal computer into a tuner. More complex and expensive tuners indicate pitch more precisely. Tuners vary in size from units that fit in a pocket to 19" rack-mount units. Instrument technicians and piano tuners typically use more expensive, accurate tuners.
  The simplest tuners detect and display tuning only for a single pitch—often "A" or "E"—or for a small number of pitches, such as the six used in the standard tuning of a guitar. More complex tuners offer chromatic tuning for all 12 pitches of the equally tempered octave.
context_section_description: A clip-on tuner clips on to an instrument—such as onto the headstock of a guitar or the bell of a trombone. A vibration sensor built into the clip transmits the instrument vibrations to the tuning circuitry. The absence of a microphone makes these tuners immune to background noise, so musicians can tune in noisy environments, including while other musicians are tuning. The clip-on tuner was invented in 1995 by Mark Wilson of OnBoard Research Corporation, which marketed it as The Intellitouch Tuner Model PT1.
