Bach’s iconic Prelude, broken into a guided path by tonebase Cello lead Mafalda Santos. Detailed fingerings and bowings, targeted exercises, intonation work, and step-by-step musical guidance help you master every measure, and understand the harmonic journey behind the notes.
Track trailerWho this Track is for
This Track isn't for everyone — and that's the point. It's a focused path for one piece, one player.
You can already play — but you practice in circles, never finishing a piece
You want one real piece, learned properly, from first note to last
You're done piecing together random videos and guessing what's next
What you'll learn · the path
Each stop is one section of the piece. Open it at your instrument and everything you need is already there.
Discover where the Prelude fits within Bach’s First Cello Suite, and how the Track’s step-by-step approach works.
Coordinate the hands without tension, anticipate each movement in the left hand, and build the string crossing patterns from open strings to smooth, resonant arpeggios.
Develop reliable shifts into second position, improve left-hand agility, and build the barred fifth in measure 8 one short exercise at a time.
Practice shifts, extensions, bowing patterns, and intonation while following the harmony from D major through a surprising diminished chord and into A minor.
Move comfortably between half, first, and second positions, then shape the diminished harmony as it resolves into E minor.
Build agility and shifting skills, establish the bowing pattern, and carry the harmonic tension toward the return to G major.
Complete the first half of the Prelude and shape the descent to the fermata: not as a conclusion, but as a question leading into a new section of the piece.
Enter the Prelude’s freer, more improvisatory second half with systematic fingering, shifting, and bowing work.
Break the passage into manageable shifting exercises, refine intonation and bowing, and shape the dissonances as part of the search for harmonic stability.
Isolate the string crossing from the C string to the A string, gradually expanding the motion while keeping the right arm efficient and relaxed.
Create space for the pitches with a clear left-hand "tunnel" and develop the small “whisking” bow motion that brings Bach’s bubbling pedal pattern to life.
Navigate the shifting and chromatic scale while maintaining momentum through one long crescendo of energy toward measure 39.
Bring the techniques and musical ideas from across the Prelude together, shaping the final measures as the culmination of the entire journey, and the long-awaited return to G major as a true arrival.

How Tracks work
Made to use while you play, not watch on the couch. This is the anatomy of a single Track section.
The passage marked up for exactly what matters — technical, musical, and interpretational — and synced to the demo.
Set your practice tempo and loop just the bars that need the work.
Clear, specific steps for how to isolate the passage, how to build it, and what to listen for. A structure, not a suggestion.
Always know the next thing to do — no guessing.
