![]() These can tune instruments and audio devices more accurately than most non-strobe tuners. The interaction of the light and regularly-spaced marks on the wheel creates a stroboscopic effect that makes the marks for a particular pitch appear to stand still when the pitch is in tune. The light shines on a wheel that spins at a precise speed. They are stroboscopes that flicker a light at the same frequency as the note. Some electronic tuners offer additional features, such as pitch calibration, temperament options, the sounding of a desired pitch through an amplifier plus speaker, and adjustable "read-time" settings that affect how long the tuner takes to measure the pitch of the note.Īmong the most accurate tuning devices, strobe tuners work differently than regular electronic tuners. ![]() More complex tuners offer chromatic tuning for all 12 pitches of the equally tempered octave. 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 (E,A,D,G,B,E). Instrument technicians and piano tuners typically use more expensive, accurate tuners. Tuners vary in size from units that fit in a pocket to 19" rack-mount units. More complex and expensive tuners indicate pitch more precisely. Since the early 2010s, software applications can turn a smartphone, tablet, or personal computer into a tuner. Simple tuners indicate-typically with an analog needle or dial, LEDs, or an LCD screen-whether a pitch is lower, higher, or equal to the desired pitch. "Pitch" is the perceived fundamental frequency of a musical note, which is typically measured in Hertz. In music, an electronic tuner is a device that detects and displays the pitch of musical notes played on a musical instrument.
