The easiest piano songs for adult beginners are melodies you already know that move mostly by step inside a small group of notes. Ode to Joy, Amazing Grace, Twinkle Twinkle, Jingle Bells, Au Clair de la Lune and When the Saints Go Marching In are where I would start. Minuet in G, the opening of Für Elise, Grieg's Morning and the Swan Lake theme are the next step up.
Why a tune you already know? Because your ear is far ahead of your hands. If you can hum a melody, you will hear immediately when your fingers get it wrong, and that is half of learning it. All ten of these are old melodies that belong to everyone, so free editions are easy to find. I am not printing any music here, only how I would think about each piece, and one practice tip for each.
Four habits for every song on this list
The same four habits apply to all ten songs, and they are the habits I use on any new piece.
Hum it twice before your hands touch a key. If you cannot hum it, you do not yet know what you are trying to play, and your hands will be guessing.
Clap the rhythm and count out loud. Count the beats, not the notes. In four-four time you say one, two, three, four in every bar, however many notes the bar holds. How to count out loud without losing your place shows the order I use.
Play hands separately for longer than feels necessary. When two hands struggle together you cannot tell which one is causing it. Separately, each hand can be listened to and fixed.
Use landmarks instead of counting up from the bottom. C is the white key immediately to the left of every group of two black keys, and F is the white key immediately to the left of every group of three. In the bass clef, middle C, the F on the fourth line and the low G on the first line are the three positions to know cold. Read every other note as a step or a skip from the nearest one. If you want the full method, see how to find notes on the piano and how to read bass clef notes.
The first six: where I would start
1. Ode to Joy
Beethoven's tune moves almost entirely by step, and its first phrase fits the five notes C, D, E, F and G under five fingers, so the hand never has to move. That is why it is the first piece in my method. In the free course it arrives in Lesson 3, which you can find in the lesson list by book page, and I teach it by ear on its own page: play Ode to Joy by ear. Practice tip: count it out loud and hold the half notes for their full two counts. It is the best place to learn that a long note still gets its counts.
2. Amazing Grace
A slow hymn tune in three-four time, built from only five different notes in its usual form, with a melody that is easy to sing. That is why adults love it: you can hear it as you play. It begins with a single pickup note before the first full bar, in most editions. It comes near the end of the free course, in Lesson 40, and you will meet the pickup measure earlier, in Lesson 15 (see the book page list). Practice tip: count one, two, three aloud, and start on the last count of the bar before the music begins, so the pickup lands inside a pulse.
3. Twinkle Twinkle (Ah! vous dirai-je, maman)
The tune is an old French melody, and it is built from pairs: C C G G A A G, then F F E E D D C. Pairs are easy to read and easy to remember. It reaches the A, one note beyond a five-finger position, so it is also your first small shift of the hand. Practice tip: find C by the two black keys, name each note out loud as you press it, and practice the leap from C up to G on its own before you play the whole line.
4. Jingle Bells
The chorus begins with E E E, twice, and then runs E, G, C, D, E, which all sit inside the C five-finger position. In the free course it is Lesson 10, played hands separately first and then together. Practice tip: repeated notes are where an adult hand tightens. Keep the fingers curved, land on the fingertips, keep the wrist level, and listen to every repeated note until it disappears before you play the next.
5. Au Clair de la Lune
An old French folk tune whose first line uses only three notes, C, D and E. It is the smallest tune on this list, which makes it ideal for a lesson in sound rather than notes. Practice tip: let the weight of your arm fall through a fingertip, release, and ask whether the second note is exactly as full as the first. Three notes are enough to practice a beautiful sound.
6. When the Saints Go Marching In
A traditional tune with a short, rising opening that is easy to hum, and an incomplete first bar, or pickup, so you start before the first bar line. In the free course it is Lesson 15, with the melody in the right hand first and then in the left. Playing the same melody in the left hand teaches you the bass clef landmarks. Practice tip: count one whole empty bar aloud before you start, at the speed you intend, so the first note arrives inside a pulse.
The next four: when both hands are ready
7. Minuet in G
A famous little dance in three-four time and the key of G major, now credited to Christian Petzold. It has one sharp, F sharp, and a left hand that does real work, so it is often the first piece in which an adult feels like a pianist. Practice tip: read the bass line first. Most people read the melody first every time, which is why the right hand gets many repetitions and the left gets few.
8. The opening of Für Elise
Beethoven's famous opening switches back and forth between E and D sharp in the right hand, a half step apart, before it falls through B, D, C to A. Learn only this opening, as a small piece in itself. The rest of the piece is not for a beginner, and nothing is lost by saying so. Practice tip: go slowly enough that the wrist stays level and the fingers stay curved, because the quick back-and-forth is exactly where tension arrives. Feel the notes in groups of three.
9. Morning (Grieg)
From the Peer Gynt music. Its melody is made of short phrases that return in a new place, and it moves in six-eight, two big beats each divided into three. It teaches you to shape a phrase, which is a different pleasure from pressing the right keys. Practice tip: count one, two, three, four, five, six, with a gentle lean on one and on four, and sing the phrases before you play them. Choose an arrangement with few sharps or flats.
10. The Swan Lake theme
Tchaikovsky's long, sweeping melody is the most demanding tune on this list, so it comes last. Simplified arrangements exist, so choose one you can read comfortably. Practice tip: play the right hand alone and sing it, and decide where each phrase breathes. Here the melody is the whole point.
Pick one, not ten
Adults often start four pieces and finish none. Choose the song you can hum best, and learn it all the way through: the hum, the count, hands separately, slowly, and then once through for pleasure at the end. When you are not sure where to begin, start the free course at Lesson 1, or book a private online lesson and I will watch your hands. For the songs people your own age most often want to play, see piano lessons for adults in their 50s and the other pages in piano lessons by age.
Questions adults ask
What is the easiest song to learn on piano?
Au Clair de la Lune is the smallest tune on my list, because its first line uses only three notes, C, D and E. Ode to Joy is almost as easy: its first phrase fits the five notes C to G under five fingers, so the hand never has to move.
Which songs are in the free course?
Ode to Joy is in Lesson 3, Jingle Bells in Lesson 10, When the Saints Go Marching In in Lesson 15 and Amazing Grace in Lesson 40. The lesson list by book page shows where each one sits.
How do I learn a piano song hands separately?
Hum the tune twice, clap the rhythm and count out loud, then play each hand alone until it is comfortable. Put the hands together only when each one is easy, and expect to go back to separate hands several times. That is not remedial. It is how the work is done.
