The electric guitar tuner is not just limited to the electric guitar; it is a tuning aid, which can help with a normal guitar as well. It relies on special sound electronics to achieve this, which rely on the very nature of sound to do its job. To understand the way an electric guitar tuner works we need to look into the nature of the sounds it is meant to meter.
The Electric Guitar Tuner and Sound
An electric guitar tuner relies on sound waves to judge the tones from an instrument. It works because every sound creates a waveform; these are the peaks and valleys of the energy that is the very nature of sound. The speed of these peaks and valleys determine the pitch of the sound.
When you are looking at the subject in more detail, you will find that the larger a waveform, the slower the rate of the valleys and peaks. This means that a deep note has a slower rate than a higher one. This is where the electric guitar tuner comes in. It is an electronic package tuned to the specific waveforms of certain notes, this allows it to compare the sound coming in to the waveform that it is tuned to, and see how close the two match.
This allows it to work on many different instruments, and still pick out the correct tones. The only requirement would be that the instrument be capable of the range the electric guitar tuner is capable of itself.
What Can An Electric Guitar Tuner Do For You?
There is the obvious of helping you get your guitar into tune by tuning it in to a note and playing that note on your guitar for comparison. Yet it can do a bit more than that. People that may have a bit of tonal trouble with their hearing also use the tuner. This lets them get a feel for the notes they are playing to be more sure that they are correct to the music.
It can also help you practice when noise may be an issue. It can let you know that you are hitting the notes without disturbing the neighbors.
