Tune up
Jam Trainer's chromatic tuner listens through your mic and shows how sharp or flat each string is — or play the built-in drone and tune by ear. Pick the banjo preset and you're set.

Read left to right: the short 5th-string drone (high g), then the 4th through 1st strings — D, G, B, D.
Standard bluegrass banjo uses open G tuning: strum the open strings and you're already playing a G chord. From the 5th string to the 1st, the notes are g D G B D — note that the short 5th string is a high g, not a low one.
A drone holds a steady reference pitch so you can hear the "beats" between two notes slow down and disappear as you come into tune. Because that's exactly how you'll check your tuning against a fiddle or another banjo in a jam, practicing with a drone trains your ear as well as your instrument.
The tuner is fully chromatic, so it handles the common alternates too — double C (g C G C D), sawmill / mountain minor (g D G C D), and D tuning (f# D F# A D). Just tune each string to the note you want; the needle doesn't care which tuning you're aiming for.
