Oh Susanna banjo
If any song earned the banjo its place in American music, it is this one — the tune whose famous line is literally “a banjo on my knee.” Oh Susanna is bright, bouncy and instantly familiar, and it uses just three beginner chords. Here are those chords, how the melody moves, and how to practise it up to speed.
The song that put the banjo on the map
When Stephen Foster published Oh Susanna in 1848, the banjo was still a young, unfamiliar instrument to most American ears. The song became a runaway hit — and its lyric, “a banjo on my knee,” is one of the most quoted lines in all of American music. More than almost any other tune, this is the song that helped fix the banjo in the public imagination as the sound of American music. That history is a big part of why it belongs on any banjo page — you can read the fuller story in our history of the banjo. It also happens to be a lovely, easy first song: a bright, bouncy melody everybody already knows, in open G tuning, using just three chords.
How the chords move
Oh Susanna is a classic I–IV–V song: you spend most of it on G, step up to C, and lean on D7 at the turnarounds before resolving home. Those are the only three chords in the whole song. Here they are in open G — the numbers are frets, 0 means play the string open, and the top line is your 1st string:
The progression itself is simple and repeats. Each phrase leans on G, touches C for colour, and lands on D7 before falling back home:
Why it is such a good first song
Oh Susanna asks for exactly one thing beyond the very first two-chord tunes: the move up to C. That single addition turns two chords into a full I–IV–V, the backbone of countless folk and bluegrass songs — so the little bit of extra effort here pays off across everything you learn next. And because the melody is one you have known your whole life, your ear does most of the heavy lifting. In Scruggs style you can play the melody notes inside a roll; in clawhammer you frail it with the classic bum-ditty motion. Either way, it sounds like the banjo the moment you start.
Oh Susanna works beautifully in both styles. If you want the driving three-finger bluegrass sound, play the melody inside a roll; if you love the older, rhythmic frailing sound, learn it clawhammer. Our guide to how to play the banjo walks through both right hands so you can pick the one that fits the music you love.
How to learn it
How you practise matters more than how long. These four steps are the difference between a song you can nearly play and one you actually own.
Before you touch the melody, get G, C and D7 clean and switching smoothly. G is every string open, so the real work is C and D7 and the move between them. Two minutes of clean chord changes beats ten minutes of fumbling the whole song.
Everyone already knows how Oh Susanna goes — use that. Hum the tune first so your ear leads your hands, then pick out the melody notes over the chords. A melody you can sing is one you will learn far faster than one you are only reading.
Play it slow enough that you never trip — even if that is painfully slow — with a metronome ticking. The bounce of Oh Susanna comes from steady timing, not speed. Nudge the tempo up only once the current speed feels effortless.
There is almost always a single spot — often the move to C or the D7 turnaround — that catches you. Isolate that one change, play it ten times cleanly, then stitch it back into the phrase. Running the whole tune to fix one bad spot wastes most of your practice.
Two things smooth the whole process. A set of finger & thumb picks give you the clean, bright tone this bouncy melody is built for, and a clip-on tuner on the headstock means every run at the song starts in tune — an out-of-tune banjo trains your ear the wrong way.

This page gives you the chords, the shape of the song and how to practise it — everything you need to start playing Oh Susanna by ear. For a written, note-for-note arrangement to read alongside it, a good banjo tab & chord book is the most reliable source — and the chords you have learned here will make that tab far quicker to read.
