A foundational arpeggio study for sound, harmony, and evenness. This page starts with full-score playback, section loops, a clickable piano, and a practice map built around harmonic groups rather than a single melody line.

About the piece
A simple pattern that teaches musical gravity.
Bach's C major prelude opens the first book of the Well-Tempered Clavier. It is built from steady broken chords, which makes it friendly to read and surprisingly deep to practice: every measure is a small harmonic event, not just a stream of notes.
The goal is not to type the notes quickly. The goal is to keep the pattern even while hearing where each harmony is going. That makes it a natural next Pianodemy test page after Fur Elise.
Practice path
Practice chords, not note soup.
Use the section buttons as harmonic areas. Start at 50% tempo, loop the opening, then move through the sequence and cadence once the hand motion feels loose.
Wait-for-note is intentionally off for this V1 page. For Bach, the guided mode should understand chord patterns and voice-leading, so playback and section navigation come first.

Questions
Before you practice.
Short answers for learners and for searchers deciding whether this is the right version to start with.
01Is Bach Prelude in C major good for beginners?
Yes, it is often approachable for late beginners because the texture is built from repeated arpeggio shapes. The challenge is evenness, relaxed hands, and hearing the harmony.
02Does this page include the full BWV 846 prelude?
Yes. The page loads the complete prelude as a playable score with section navigation and tempo controls.
03Why is wait-for-note not enabled here yet?
This V1 page is playback-first. Bach needs a different guided-practice model because the learning unit is usually a chord pattern, not a single right-hand melody.
04What should I focus on first?
Start slowly and group each measure as one harmony. Keep the repeated pattern even before increasing tempo.
How to use this V1
Let the harmony carry the hands.
Loop short groups, keep the repeated pattern even, and listen for the top note of each measure. Speed comes after the chord shapes feel automatic.
