Tuners are great tools for students, teachers, professionals, or those who just love to play!  Used to show if tones are sharp (too high) or flat (too low), they help players develop their intonation.  Here is a quick guide to some terms and features of these devices.

LCD Display
(Liquid Crystal Display) This display shows a simulated needle electronically.  Other models without an LCD will show an actual needle.

LED Display
This refers to the red or green lights found on some metronomes that blink to show the beat.

Calibration
This refers to the frequency of a pitch.  Most orchestras in the United States tune to an A=440Hz calibration while European orchestras generally tune to A=442Hz.

Octave
An octave is the interval between the first note and the eighth note of a scale.  These tones have the same letter.

Tone Generation
The tuner generates reference tones if it has this feature.

Transposition
The shifting of one or more groups of notes up or down while maintaining the same intervals.

Sound Back
Once a pitch has sounded by the player, the tuner plays it back exactly how it was recorded regardless if it was in or out of tune.  

Power Adaptor/Power Adaptor Jack
Some metronomes have the option of plugging into a power outlet using a power adaptor instead of battery operation.

Tuner & Metronome Combinations
Shar offers several metronome and tuner combinations.  This allows for convenient use of either a metronome or tuner in one compact device.
