Six to twelve weeks.
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?
Needs decay and the low octaves. The piece lives on the bass ringing on – on light keyboards little is left.
