Standard Guitar Tuning Guide
Standard tuning is the most common way to tune a 6-string acoustic or electric guitar. Knowing how strings are tuned is fundamental when learning how to play guitar online.
The 6 Strings: Notes & Frequencies
Guitars are tuned from the thickest string (6th string, lowest pitch) to the thinnest string (1st string, highest pitch). Standard tuning uses the notes **E-A-D-G-B-E** (often memorized using the mnemonic: *Eddie Ate Dynamite Good Bye Eddie*).
Tuning Frequencies
Each string is tuned to a specific pitch frequency measured in Hertz (Hz). For example, the 5th string (A2) is tuned to 110Hz, which is exactly two octaves below the standard orchestra tuning reference pitch of A4 (440Hz).
Understanding these frequencies is helpful when using digital chromatic tuners. Our **online guitar tool** is pre-configured to standard tuning, allowing you to hear reference tones for tuning a real-world physical guitar.
How to Tune Your Guitar
1. Use a Tuner App
Download a free chromatic guitar tuner on your phone, or use a clip-on tuner. Pluck the string and adjust the peg until the needle reaches the center.
2. Tune Up, Not Down
If your string is too sharp, tune it slightly below pitch and then tune *up* to the pitch. This prevents string slippage and keeps it in tune longer.
3. Reference Tuning
Play the open string notes on our virtual guitar simulator to hear what the correct pitches sound like, and tune your physical guitar by ear.
