Practice Journal - Toccata in C minor BWV 911 - J.S Bach

While learning the opening section of Bach’s Toccata in C minor BWV 911, I encountered a challenging four-voice fugal passage on the second page. The complex nature of managing multiple independent lines made it difficult to identify and balance each voice clearly. To combat this, I used coloured pencils to mark out the different voices, which helped me visually see the individual lines and better understand how they interacted with one another. 

I began by practising each voice separately to become familiar with its melodic shape and direction. Once I was comfortable with the individual parts, I gradually combined two voices at a time, then three, before bringing all four together. Practising at a slow tempo was essential, as it allowed me to maintain clarity and balance between the voices rather than focusing solely on accuracy.

Another challenge was deciding on suitable fingering. Since each voice carries its own melodic importance, the fingering needed to support phrasing and preserve the continuity of each line. I experimented with several options before settling on fingerings that felt natural to me and allowed the voices to remain connected.

As I became more familiar with the texture, I also paid close attention to where the fugue subject reappeared and how it interacted with the countersubject. Recognising these entries helped me shape the musical structure more effectively and bring out the important thematic material.
