And btw, it's Scherzi, not scherzos. Chopin would be mad at you, Chopinlover01
Entirely depends on which etudes you're talking about and what standards you're planning to meet when you term something as being "learned".I'm currently working though the Scherzi and Ballades, performed the 1st and 3rd scherzo last weekend actually. 2nd one is most approachable, but has some demanding parts, You'd likely enjoy learning it. 1st one sounds incredible when played well, but you need to be very experienced i find to manage it. Relatively few notes to learn in comparison, but it sounds like there are many, and you need remarkable control at high velocity. 3rd one is more demanding. I have yet to approach the 4th one yet. They make a fine recital group all of them, future project i sometimes think about.
Just print the first few pages, the middle part and coda. Memorize the small changes on repeats. Its a 5 page piece.
On the UK diploma exam syllabus, Ballade No 3 belongs to the associate level, while the other 3 ballades, the 4 scherzi and the etudes Opp 10 & 25 belong to licentitiate level.Both his ballades and scherzi are musically and technically demanding, though the ballades will deem to be more story telling.Good analysis and planning of playing any ballade or scherzo is required. Themes / sections get repeated, and the player ought to think and play each time (slightly) differently. This is from a masterclass.Good luck!
The Licentitate diploma syllabus:- any two contrasting etudes from the same opus set of Op. 10 and Op. 25,- any of the 4 scherzi- ballade no 1, 2 or 4amongst other Chopin and non-Chopin works.The 3rd ballade is the easiest amongst the 8 ballades and scherzi in that sense.
