Chopin Sherzo Op. 31 No. 2
Session 1 63-69
...
Session 78 759-764
Session 79 765-775
I spent almost an hour to count the bars of sherzo no.2. Phew. Is it ok like this?
I think it needs a few more session for a whole phrase to be played together.
Ok. You have divided the piece in small sections. But the way you did it, you will need 79 sessions. Even if you can deal with one session a day, it is going to take you almost three months to master all these sessions, and then you will need to put it altogether.
Have you had a good look at the score (while listening to the CD)?
Let us examine just the first 264 bars of this piece.
I will not organise it in terms of difficulty (which I suggest you eventually do, that is work on the most difficult sessions – for you – first), but from bar 1 to bar 264,so you get an idea what you should be trying to do.
The first 264 bars can be mastered by tackling it as seven practice sessions only. How?
First practice session: Bars 1 – 48.How can you tackle such a long passage in a single practice session? Simple: there is a lot of repeats. In fact this whole piece is so repetitive that you can learn it by learning about 60 – 70 bars. In this particular session you start bay working on bars 1 – 9. This should be easy enough. If you have problems memorising the chord sequence in bars 6 – 9, isolate it for repeated-note-groups treatment.
Having mastered bars 1 – 9, go straight to bars 14 – 17, they are almost identical to bars 6 – 9. Again use repeated note-groups. There are only 5 chords, so this should take 5 minutes at the most. Bars18 – 24 are quite elementary, so you should be albe to learn them in a couple of minutes.
Now simply join together bars 1 – 24. Easy? I thought so.
Bars 25 – 48 are an almost repeat of bars 1 – 24. The differences are in bars 30 – 33, bars 38 – 41 and bars 42 – 48. Again, work on these three sections in isolation and then join them together from bar 25 – to bar 48.
Finally put together bars 1 – 48. You should be able to master this in 20 – 40 minutes easily.
Now just keep repeating this section in the days to come (while you are tackling the other sessions in parallel). This is quite a large chunk – and very important in the piece too – so as soon as get the technique (movements, fingerings and so on) under your belt start straight away working on the musicality. Do not be fooled by the apparent simplicity of this first session. In particular the pair of triplets can be a real nightmare to get just right.
Second practice session: Bars 49 – 65. Learn this hands separate first. You may have to work quite a while on the scale runs until they become fast and smooth. Again there is a lot of repetition: bars 49 – 52 are the same as bars 57 – 60, so concentrate in getting bars 49 – 52 absolutely prefect and then you will not need to waste any time in bars 57 – 60. Likewise the RH of bars 53 – 56 is the same as bars 61 – 64. And – listen to this! – the LH of bars 62 – 64 is again exactly the same figuration but one octave lower. So you can alternate hands in this passage: play RH bars 53 – 57 and then LH bars 62 – 64. Once you get the hang of these smaller sections, start putting them together. Again, you should be able to master this whole passage in 20 – 30 minutes.
So, the first day you mastered session 1; the second day you are still working on session 1 but starting to direct your attention to the more musical aspects of the passage, and you are also learning session 2.
The third day you continue to work on these two sessions, polishing and perfecting them, and you start on practice session 3.
Third practice session: Bars 65 – 96.Have you noticed that the first bar of this section is the last bar of the previous section? This will provide for an overlap. Whenever you break down a piece in sections you must
always overlap sections in order to avoid hesitations and stuttering when you join the section later on.
Now this may seem like a hefty section to tackle, and it is. However the figurations are very similar and the texture is straightforward: melody in the RH, arpeggio accompaniment on the LH.
You are going to break down this section in three workouts.
1. Outline. Rewrite the score so that you only have the RH melody , and on the left hand the first note of the arpeggio figuration. Learn this whole passage with hands separate, then join hands. At the end of it you should be playing the melody accompanied by the bass notes – without the fast arpeggio figurations. This should be easy. At the same time, you can concentrate completely on musicality, since the technique to play it in outline is trivial.
2. Left hand figurations. This is the true difficulty in this practice session. There are 32 bars, and they rarely repeat (If you ignore the first bass notes, and only look at the five next notes, you will see that bar 65 = bar 83; bar 66 = bar 70; bar 68 = bar 71; bar 74 = bar 77; bar 76= bar 79, bar 80 = 81 = 82; bar 85 = 86; bar 89 = bar 90; bar 91 = 92 and bar 93 = 94).
The best way to tackle the left hand is to do repeated note-groups, taking each bar as a unity. Divide the 32 bars into 8 bars and apply repeated note groups to each of these 8 bars. This will take something like 45 – 60 minutes per 8 bars, so you will not be able to tackle this practise session in a single day (unless you do several practice sessions in a day on it).
So, if you dedicate one practice session a day for this piece, this third practice session will require a minimum of six days to cover: One day for the outline; four days for the LH and the last day for HT (see below).
3. Having mastered the outline of this passage, and having mastered the left hand, now you must put back the arpeggio figurations in it. The best way to do that is to keep the LH going and drop the RH notes one at a time.
Fourth practise session: bars 96 – 117.This is really a recap of the previous session with the melody being played in chords. Again follow the same scheme: outline, LH and hands together. Except that now most of the LH figurations will have been mastered, so you should be able to tackle this practice session in 20 – 40 minutes.
Fifth practice session: bars 117 – 130.
Piece of cake. No difficulties here. (Meanwhile you are still working on the other practice sessions in parallel)
Sixth practice session: Bars 1 – 130Now you are going to join everything you have been working on so far. Most of the work here will be making sure the transitions are smooth (they should be, we have been overlapping all along) and working on the musicality of it all.
Seventh practice session: Bars 1 – 264What? 264 bars?
Yes, it is all a huge repeat! The only bars that are slightly different are the following:
Bars 148 – 149; bars 172 – 173; bars 179 - 180 and bars 233 – 234.
Start the practice session by thoroughly mastering these 8 bars, and then put the whole thing together.
There! 1/4 of the piece mastered and memorised in seven practise sessions and twelve days (hopefully).

In fact it is more than 1/4, since this whole section will repeat later on.

Of course, you should not move to the next session until the one you are in is mastered, so it may take you more than 12 days to cover these 7 practise sessions. It may also be that the size of sessions I suggested may be overambitious (a beginner would never be able to do it – but a grade 8 student should have no problems).
In any case, my main point here was to show how the division in sections is a consequence of analysing the score: seeing which bits repeat, so you don’t need to practise more then strictly necessary, and you go on to playing the piece as soon as possible.
I will leave the rest of the piece for you to organise in sessions as homework.

Best wishes,
Bernhard.
