History

What to listen for
A broad melody above running detail
Long upper notes and ornaments unfold above a continuous lower pattern and short inner chords. Hear the melody through the smaller motion.
The song changes while its support continues
Changing upper phrases sit above new bass cells and detached inner attacks. Listen to the melodic direction without losing those supporting changes.
Presto brings a more mobile upper line
The printed Presto introduces upper running figures while the lower pattern continues. Hear the new interaction, not the hidden numeric playback setting.
Short flourishes lead to a broad E close
The final scale and separated upper notes settle onto E as the lower strands complete the close. Hear their different routes toward the same arrival.
How to practise it
Long upper tie and ornament; short inner chords followed by rests.
- Keep the longer melodic line audible while practising its short decorations.
- Count the chord attacks and their following silence instead of sustaining them throughout the upper phrase.
How hard is it
The expressive opening and quicker continuation require contrasting touch, coordination and secure pacing.
