The Ultimate Guide to the 6-String Ukulele: Finding and Using the Best Online Tuners

If you’ve recently picked up a 6-string ukulele (often called a guitalele hybrid, a six-string tenor, or a guitalele-style uke), you already know how unique and rich its sound is. By adding a low-G and a doubled octave (or paired courses) to the traditional setup, a 6-string ukulele delivers a fuller, more guitar-like resonance while still keeping that unmistakable island charm.

However, tuning a 6-string instrument can be tricky if you are relying on a standard 4-string ukulele app or a guitar tuner that doesn’t recognize your specific configuration.

Whether you are prepping for a jam session or restringing your instrument for the first time, here is everything you need to know about tuning your 6-string ukulele using online tools, along with step-by-step instructions.

Understanding Your 6-String Ukulele Tuning

Before diving into online tuners, it is vital to know how your instrument is actually supposed to sound. Unlike a standard 4-string ukulele (tuned G-C-E-A), a 6-string ukulele typically follows a guitalele tuning standard, which mirrors the top four strings of a guitar plus two extra strings, or a standard tenor layout with doubled courses.

The most common tuning for a 6-string ukulele (Guitalele style) from lowest pitch (thickest string) to highest pitch (thinnest string) is:

• A (Low A – 5th string of a guitar)
• D (Low D – 4th string of a guitar)
• G (Low G – 3rd string of a guitar)
• C (C4 – 2nd string of a guitar)
• E (E4 – 1st string of a guitar)
• A (A4 – doubled high octave or unison depending on the model)

Quick Tip: Always double-check your instrument’s manufacturer guidelines or string package. Some boutique 6-string ukuleles use a traditional re-entrant ukulele tuning (like a standard uke with doubled strings), while most mass-market 6-strings (like Kala or Ortega guitaleles) use A-D-G-C-E-A.

How to Use an Online Tuner for a 6-String Ukulele

If you don’t have a physical clip-on tuner handy, browser-based microphone tuners or tone-generator websites are your best friends. Because many standard online tuners default to a 4-string uke or standard guitar (E-A-D-G-B-E), you need to know how to adjust them.

Method 1: Chromatic Microphone Tuners (Recommended)

A chromatic tuner detects any musical note you play and tells you if you are sharp (too high) or flat (too low).

1. Find a reliable online chromatic tuner: Websites like Tuner-Online.com, MuseScore Tuner, or Guitar Tuna’s web version work directly in your browser.
2. Grant microphone access: Allow your browser or device to use your microphone when prompted.
3. Pluck string by string: Starting from your lowest string to your highest, pluck a single string and watch the needle or digital display:
   • If the indicator leans to the left (or red), your string is flat—tighten the tuning peg slightly.
   • If the indicator leans to the right (or red), your string is sharp—loosen the tuning peg.
   • When the light turns green or centers on the exact note name (A, D, G, C, E, A), you are perfectly in tune!

Method 2: Reference Tone Generators (By Ear)

If your computer microphone isn’t picking up sound well, you can use an online audio tone generator (like OnlineMicTest Tone Generator or YouTube reference tracks) to match pitches by ear.

• Play the target note tone through your speakers/headphones.
• Pluck the corresponding string on your 6-string ukulele.
• Adjust your tuning peg until the sound waves “lock in” and the pulsing sound (beats) disappears, meaning both frequencies match.
