What to listen for
A continuous line above detached attacks
Upper sixteenths continue above detached lower attacks and rests. Hear the longer running direction without filling the lower gaps.
Registers and bass supports change
Related moving cells shift register above changing bass supports. Listen to the changing foundation within the continuous upper pattern.
Low A supports chromatic expansion
Sustained low A underlies denser chromatic motion. Hear the added colour without losing the long foundation.
Separated chords make a held arrival
Arpeggiated chord responses interrupt the running texture and lead to a full fermata chord. Hear the change from motion to sustained arrival.
How to practise it
Lower start followed by climbing high pitches; longer low attacks against shorter moving notes.
- Hear the initial low attack as preparation, then practise the high ascent and return with evenly spaced small steps.
- Maintain the longer low-note duration while the higher line continues its shorter attacks; do not release both layers automatically at every high-note change.
How hard is it
Brilliant broken-chord motion requires evenness, clean coordination and harmonic direction rather than unshaped speed.
