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. A fiddle tunes to the same G D A E as a mandolin, so pick that preset and you're set.

Low to high: G, D, A, E — each string a perfect fifth above the last. A fiddle is a violin, so the tuning is identical.
A fiddle is tuned in perfect fifths — from the lowest string to the highest, G D A E. It's the exact same tuning as a violin (a fiddle is a violin — "fiddle" just describes the old-time and bluegrass playing style) and the same four notes as a mandolin.
Old-time and bluegrass fiddlers live and die by their ear, so it's worth learning to tune without staring at a needle. Play the drone on a string's target note and match the string to it — when the two stop "beating" against each other, you're in tune. Because a jam won't pause for you to plug in a tuner, that skill pays off fast.
Once you're close, the real test is playing along. Pull up a tune in Jam Trainer and you'll hear immediately whether your fiddle sits right on top of the guitar and mandolin, or whether a string has drifted. So tune first with the needle, then let your ear confirm it against a full band.
