Question 1

Do I need a microphone?

Accepted Answer

No! This tuner plays reference tones that you match by ear. Unlike microphone-based tuners, no audio input is needed — just listen and tune your strings to match.

Question 2

What is standard guitar tuning?

Accepted Answer

Standard tuning for a 6-string guitar is E-A-D-G-B-E (from lowest/thickest string to highest/thinnest). The frequencies are: E2=82.41Hz, A2=110Hz, D3=146.83Hz, G3=196Hz, B3=246.94Hz, E4=329.63Hz.

Question 3

Can I use this for other instruments?

Accepted Answer

While designed for guitar, you can use the reference tones for any instrument that shares these notes. For example, the E, A, D, and G strings match the tuning of a bass guitar's top 4 strings (though bass is one octave lower).

Question 4

Why can't I hear the tone?

Accepted Answer

Make sure your device volume is up and not muted. Some mobile browsers require user interaction before playing audio. Try clicking the string button again. Using headphones can also help you hear the pitch more clearly.
