How difficult is it?

Five flats, frequent metre changes within the flow, hands crossing and a sound world that does not emerge without fine pedalling. Often underestimated because it sounds calm.

The real hurdle

Five flats, constantly shifting metre and divided hands. Without half-pedalling the sound simply does not appear.

How long does it take?

A year of preparation is realistic; the opening bars come faster.

A rule of thumb, not a rule – how fast it goes depends on prior experience and practice time. This level is an assessment, not a measurement: most pieces exist in arrangements ranging from heavily simplified to concert level. The rating refers to the common arrangement.

Which instrument suits it?

Makes the highest demands on this list regarding touch and pedal – a real hammer action with half-pedalling makes the difference here.
