What to listen for
Slow entries gradually fill the texture
The slow bass line is joined gradually by other sustained entries. Hear each new strand arrive without losing the earlier long sounds.
A flowing strand changes the texture
A running eighth-note strand enters while sustained gestures continue elsewhere. Listen for the new flowing layer alongside the longer notes.
Contrasting kinds of motion circulate
Sustained, flowing and repeated-note textures move among five strands. Follow a chosen kind of motion as its register changes.
Long supports carry the final C-sharp
Extended low support and changing inner parts continue beneath a tied upper C-sharp. Hear the active layers gather into the final cadence.
How to practise it
Carry the long chromatic subject while keeping later voice entrances distinct.
- Sing the subject slowly and name B-sharp distinctly; play it with counted full durations rather than shortening the whole notes.
- Count the tenor's silence against the opening bass subject, then add its entrance without making the earlier line disappear.
How hard is it
Dense contrapuntal development requires sustained attention to several simultaneous lines and a convincing large-scale arc.
