K. 1c Allegro in F
di Wolfgang Amadeus Mozart
The Five‑Year‑Old Mozart and His Allegro in F, K. 1c
Wolfgang Amadeus Mozart wrote his first compositions at an age when most children are just learning their ABCs.
One of those pieces – the Allegro in F major (catalogued as K. 1c) – stands as an early testament to his extraordinary talent. Composed in 1761 when Mozart was only five years old, this short keyboard work offers a glimpse into the musical world of the young prodigy and the nurturing environment crafted by his father, Leopold.

A Childhood of Music (and a Little Play)
Mozart’s days as a toddler and young boy were anything but ordinary. He was home-schooled by his father Leopold, who was an accomplished musician and teacher.
Leopold taught Wolfgang and his older sister Maria Anna (nicknamed “Nannerl”) not only music but also languages and basic academics – yet music was clearly the main focus.
By the age of five, Wolfgang was already playing the harpsichord and violin and even writing little pieces of music. In fact, as his sister later reminisced, “at the age of five, he was already composing little pieces, which he played to our father who wrote them down”.
Music wasn’t a forced chore for the boy; on the contrary, he loved it so much that his family sometimes had to pull him away from the keyboard after long hours, rather than push him to practice.
By the time most kids might start school, Wolfgang was performing for princes and empresses. At just five and six he appeared in the courts of Europe: he gave his first public performances in 1762, astonishing the aristocracy in Munich and Vienna.
Famously, after one concert in Vienna, the six-year-old Mozart even jumped into Empress Maria Theresa’s lap and kissed her – a bold, playful act that delighted the royal court.
Such anecdotes illustrate that Mozart’s social life was often in palaces rather than playgrounds. In short, his childhood was filled with music, travel, and adulation from nobles, leaving little time for a typical school or neighborhood friendships.
Father and Son Compose a Melody
Within this musical childhood emerged the piece known as K. 1c, Allegro in F. Mozart composed it on 11 December 1761 in Salzburg.
Of course, at age five Mozart couldn’t yet write notation clearly, so Leopold acted as his scribe – Leopold wrote out the notes in Nannerl’s music notebook while Wolfgang played and improvised. In the surviving manuscript, the handwriting is Leopold’s, but the musical ideas are understood to be little Wolfgang’s own.
How much did the father contribute? Leopold was an experienced composer and teacher, so he certainly guided his son, giving feedback and basic exercises in composition. However, contemporary evidence (including Leopold’s letters and Nannerl’s recollections) suggests that the creative spark was Wolfgang’s, with Leopold merely polishing here and there.
In fact, Mozart’s earliest pieces were essentially father–son collaborations, with the boy inventing the tunes and proud Papa ensuring they were properly written down and lightly refined.
It’s important to note that Mozart’s talent at that age was very real – observers in the Mozart household marveled that such a small child could come up with harmonious melodies on his own.
A Lively Little Allegro in F
In keeping with its title “Allegro” (Italian for “cheerful” or “fast”), the piece is bright, quick, and playful. It was written for harpsichord, the keyboard instrument Mozart had at home.
The music itself is very short – 24 measures long, including repeats – yet it has a clear structure.

Mozart composed it in rounded binary form, meaning there are two sections (each repeated) and the second section ends by circling back to the main theme of the first.
In practice, it comes across like a charming little dance. In fact, one commentator compared K. 1c to a “jolly south German folkdance” in character.
The piece is in the key of F major, making it Mozart’s earliest surviving work in that key. The style is simple and tuneful – you won’t find deep complexity here, but for a five-year-old’s invention it is musically coherent and joyful. Listening to it, one can imagine the tiny Wolfgang happily bounding across the keyboard with his small hands, producing a melody that bubbles with energy.
