Learn 160 Eight-Measure Exercises No. 6, Op. 821
An Andantino in F major and 3/4 that tests slow-tempo control — arguably harder than fast passages because every unevenness between fingers is fully audible. Set the tempo slider to the marked Andantino and resist the urge to move it — the practice desk's slow playback mode reveals exactly which fingers are uneven in a way that faster tempos conceal.

About the piece
The counterintuitive truth: slow is harder.
Carl Czerny — Beethoven's pupil and Liszt's teacher — understood that students instinctively rush through slow exercises to reach the technically impressive fast ones. The 160 Eight-Measure Exercises, Op. 821, counter this tendency by placing a deliberate Andantino immediately after two faster pieces in F major. No. 6 is not a rest: it is a diagnostic tool. At slow tempo, every inequality between fingers is fully exposed; at Allegro it would be hidden.
No. 6 stays in F major and 3/4, sharing its key signature and metre with No. 5, but shifts the demand entirely from expressivity to evenness. Where No. 5 required dynamic shaping and singing tone, No. 6 asks only that every note sound identical — same length, same weight, same timing. That constraint is far more revealing than it looks on the page.
Practice path
Match every note to the weakest one.
Play the exercise once and identify the weakest-sounding note — usually produced by the fourth or fifth finger. Set that note's volume as the target for every other note in the exercise. This sounds counterintuitive, but equalising downward first, then gradually building the weaker finger, is faster than trying to suppress the stronger fingers one at a time.

Questions
Before you practice.
Short answers for learners and for searchers deciding whether this is the right version to start with.
01Why is a slow exercise like Czerny Op. 821 No. 6 useful?
Slow tempos expose unevenness between fingers that fast playing disguises. Practising at Andantino forces each note to stand on its own, building the finger independence needed before speed is added.
02How does Czerny Op. 821 No. 6 differ from No. 5?
Both are in F major and Andantino, but No. 6 stays in 3/4 and shifts the emphasis from expressive shaping to pure evenness of touch — a subtle but distinct technical target.
How to use this V1
Slow tempo, strict metronome, no exceptions.
Set a metronome and do not adjust it upward during the session. Any acceleration means a finger is rushing to compensate for a weak predecessor. At Andantino, sustained notes must ring their full duration before being released — lifting early is as uneven as playing late. Count the rests silently at the same internal tempo. Use the section loop on any bar where a note clumps or fades before its neighbours.
