Most tuners use a microphone to pick up these frequencies and compare them to these six programmed frequencies. Here are the frequencies associated with each string, starting from the thickest string at the bottom to the thinnest at the top: Thicker strings vibrate slower than thinner strings do. The higher the frequency, the higher the note.
The standard adult ear can only hear between roughly 8 Hz to 14,000 Hz.Įach note has a specific Hertz number associated with it based on the frequency of the soundwaves for that note. The frequency of those waves is measured in Hertz (Hz), or how many times those waves vibrate per second. When you pluck a string on a guitar, it vibrates, creating a sound wave that reverberates out from it. Without getting too deep into the physics of it all, every sound is actually a vibration or a sound wave. Guitar tuner apps are suitable for quiet environments without too much ambient noise. However, if you intend on playing some open mic nights when the world opens up again, you’ll probably want to invest in a clip-on tuner.
So don’t worry, your neighbor probably doesn’t want to scream from out-of-tune chords. If you’re just practicing at home, the technology in your smartphone microphone is powerful enough to accurately tune the strings on your guitar. If you’ve picked up guitar since quarantine began, you’ve probably been using one of many different guitar tuner apps on your smartphone.
