How to Tune a Banjo
Tuning your banjo is the first step to making great music. The standard 5-string banjo tuning is Open G (gDGBD). The strings are numbered 1 through 5, with string 1 being closest to the floor and string 5 being the short drone string that starts at the 5th fret.
The 5th string is tuned to a high G, which acts as a drone note and gives the banjo its characteristic ringing sound. This re-entrant tuning, where the shortest string is the highest pitched, is what makes the banjo unique among stringed instruments.
How to Use This Banjo Tuner
- Select your tuning from the dropdown menu (Standard Open G is selected by default).
- Click the microphone button and allow microphone access when prompted.
- Pluck a single string on your banjo. The tuner will automatically detect which string you're playing.
- You can also tap a specific string button to tune that string. The tuner will show how sharp or flat you are from the target note.
- Turn the tuning peg until the indicator is centered and the status shows "In Tune."
- Repeat for each string until your banjo is fully in tune.
Understanding Banjo Tuning
Standard Open G (gDGBD) — The most common tuning for 5-string banjo. Used in bluegrass, Scruggs-style three-finger picking, and most popular banjo music. The open strings form a G major chord.
Double C (gCGCD) — A popular alternate tuning used extensively in old-time and clawhammer banjo playing. Creates an open C chord and is used for many traditional Appalachian tunes.
Sawmill / Mountain Minor (gDGCD) — A modal tuning commonly used in old-time music for minor-key tunes. Also known as Mountain Minor tuning, it produces a haunting, modal sound.
