How to play Sonatina in C Major, Op. 20 No. 1

Tempo:Take the Allegro at a cheerful, moderate speed where the scales and triplets stay clear. Let the six-eight Andante sing without dragging, and keep the rondo light and unhurried.
Right hand:Shape the scale runs as single gestures, with a small lift at the top and a gentle landing at the end. In the Andante, make the top line sing.
Left hand:The left hand supplies Alberti-style broken-chord patterns and plain bass notes. Keep it even and soft so the right-hand tune is always on top.
Hands together:Practice hands together at a slow tempo with a metronome, especially where the right hand runs scales over a steady left-hand pattern. Check that the hands arrive at phrase ends together.
Rhythm:Keep the beat steady through scales and broken chords. A slight rush at the top of a run is the most common rhythm slip in these sonatinas.
Dynamics:Use clear contrasts of loud and soft between phrases, in the style of Mozart. In the first movement, let the forte minor-key triplets storm and then drop to a true piano for the dolce second theme.
Reading:The outer movements have no key signature but the minor-key passages bring in flats and naturals, and the Andante has one flat. Scan ahead for accidentals before each new section.
Practice:Learn each movement separately, and within each, learn the main theme, then the contrast, then the return. Join the sections only when each is secure.

Common mistakes

Playing scale runs unevenly, with the thumb crossing heavily. Fix: Practice the scale slowly with a loose wrist so the thumb passes under without a bump.
Letting the Alberti bass in the left hand grow louder than the melody. Fix: Practice the left hand softly alone, then bring in the right hand over it.
Rushing the rondo because it is cheerful. Fix: Keep the metronome at a moderate tempo and aim for lightness, not speed.
Treating every phrase with the same dynamic. Fix: Mark the high point of each phrase and let the notes before and after be softer.

Structure: three-movement sonatina (fast - slow - fast)

The first movement is a small sonata form in C major, with a stormy C minor passage in triplets and a gentle second theme marked dolce. The second movement is a short, peaceful Andante in F major in six-eight. The finale is a good-natured rondo in two-four, with a middle section in the minor before the main theme returns.

I · Allegro (C major): A bright movement that opens on a rising C major arpeggio over an Alberti bass, then contrasts loud minor-key triplet arpeggios with a sweet, singing second idea. Scales and broken chords are the core reading material.
II · Andante (F major): A short, calm, songlike movement in a gently rocking six-eight, for practicing a singing right hand over a quiet accompaniment.
III · Rondo: Allegro (C major): A cheerful rondo in two-four whose dotted main theme keeps returning, with a minor-key middle section for contrast. The challenge is keeping light, crisp passagework steady.

About Sonatina in C Major, Op. 20 No. 1

Friedrich Kuhlau (1786-1832) was born near Lüneburg in Germany, fled to Copenhagen in 1810 to avoid conscription into Napoleon's army, and became a Danish subject in 1813. He lost his right eye in a fall on ice at age seven, became a concert pianist and opera composer, and introduced many of Beethoven's works to Copenhagen audiences. His flute works earned him the nickname the Beethoven of the flute, though he did not play the instrument.

The three sonatinas of Op. 20 were published in 1820 and were probably written for amateurs or as teaching pieces. They are often studied by intermediate pianists as a step toward full Classical sonatas, alongside Clementi's Op. 36 sonatinas.

The first sonatina is in C major. Its opening bar is strikingly like the start of Mozart's Sonata in C major, K. 545, and the whole work shares the clear phrases, tidy forms and lively contrasts of Mozart's style.

A fire destroyed Kuhlau's unpublished manuscripts, yet more than 200 of his published works survive.
