Could I possibly have that PM as well?!

I know there have been many threads on memorising but I still keep reading in the hope of having a Eureka moment. (No, it's not my forte either...) As long as it's not personal, I'm sure others wouldn't mind it being long either if you were to post it here.

The document I compiled is based on stuff that I've read, in books and on various forums, and on observing how my own teacher works. So I don't want to present it as my own work but rather a summary of what has worked for me, when previously I would panic at the idea of trying to learn even a few bars around a tricky page turn!
For me the big help was learning how to identify what constitutes a small section, and the huge reassurance of finding that it's quite normal to have forgotten it by the next day!!
How to memorise a piece for non-memorisers
The essentials boil down to;
a) creating as many different associations/pathways into your long-term memory LTM as possible
b) knowing how to organise the music to be learned into small enough chunks that your short-term memory STM can hold. (This amount is around 7 + or – 2 items of information; this could be for example seven separate notes, or seven pages depending on the complexity of the music and your level of musical knowledge.)
(To begin with choose a piece that you haven’t tried to learn before. Otherwise you’ll be battling with previous mistakes and frustrations)
Ingredients
Photocopy of score to use as working copy.
Coloured pencils, small post it notes
A way to record your memorising progress for the piece, eg a notebook, or use the back of the photocopies or make a squared chart or …
Preparation away from piano
Listen to as many different recordings as poss. Think about what you like/find meaningful in them
Familiarise yourself with the score. When listening, read the score. It often looks very different to how you expect.
Identify main musical sections, themes, developments and such like and mark on the score. These may be just letters or numbers but the more meaningful to you the better e.g. give each section a name, might be an emotion or visualisation it evokes. Use colours to highlight dynamics, write key words describing mood or colour or interpretations of sections on post-its (saves erasing as your interpretation modifies as you learn)
Do some basic analysis of the piece; at least know its predominant key and key changes
Number the bars
Find all the repetitions you can; phrases, lines, whole sections often repeat. Cross them out or bracket them. This is highly rewarding … the total number of bars to be learnt can diminish dramatically
At the piano
Sightread through as best as you can to find which bits will be most difficult for you. Make a note of them
Make a practice plan. How much time do you have each day? In what order will you learn the piece? It’s a good idea to start with the sections you have identified as most difficult, as they will need the most practice. You could start with the last line or section and work backwards, this way you are always playing towards something you know.
Practice session nuts and bolts
Choose a small chunk that you think you can memorise. Let’s say it’s a six bar musical phrase. I’ll call it 1-6 (Also add one or two notes from the next bar as an overlap. This helps when you start to join up the small chunks later)
Investigate this chunk;
Work out the fingering and arm movements for each hand separately (HS). If the piece is a fast piece, make sure that this fingering will work at a fast speed. If you have chosen a small enough section, you should be able to test this at speed. Very important to do this otherwise you will hit a speed wall eventually if the fingering chosen is not suitable. Spend as much time as necessary on this, trying to find the movements that are easy and comfortable. Teacher input is really valuable at this stage.
Try to do some analysis of the harmony. Even if you’re pretty incompetent at this have a go! You can probably identify some basic chords, bits of scales that appear, this bit's going in thirds, here the pattern of notes is repeated but a fifth up, or whatever. … the professionals say this is at the heart of secure memorisation.
Now work on this small chunk HS with the score. Each time you play it you must give it full attention. Best way to keep attention sharp is to focus on a different aspect each time; eg
-fingering and arm movement
-what does my hand position look like on the keyboard eg lots of black notes/ fingers close together/ pattern of black and white keys …. (Very important if you’ve always been drilled to keeping your eyes glued to the score)
what do the movements feel like/close eyes
--rhythm
-articulation (staccato, legato etc)
-dynamics
-relaxation, does it feel comfortable
-sing as you play, am I bringing out the melody
-name notes as you play
-note what’s happening with the melody /harmony
-anything else you can think of e.g. which notes of a chord to bring out; is there something particularly interesting in this little section …
Take a few moments at the end of each little play to mentally note what you just did. Don’t just rush headlong from repetition to repetition
Moment of truth
You have now played this small section with full attention several times HS. It’s probably taken less than 10 mins. Put the score away and play it from memory.
If you can’t do it, the section was too long for your short term memory to cope with. Cut it in half. Go through exactly the same procedure with only three bars. Test again. Still not remembered? So be it, do just one bar.
(sounds horribly laborious? But if you have to do the pruning procedure, it takes much less time than the first try. Also you quickly get better at recognising what size chunks work best for you and depending on how complex the music is. Better to err on the side of choosing very small bits first if you are not a natural memoriser.)
This chunk is now somewhere on its journey into your long term memory (LTM). You now strengthen the memory trace by practising it without the music correctly 7 times. (many more and you start to lose concentration) This means playing slowly, correctly, relaxed and with full attention. You are only putting correct information into your brain, and ingraining correct movements. Again, to keep concentration, focus on a different aspect of the music each time as you did above. Pause, relax and refocus between each play. When you have played it correctly 7 times,
leave that chunk alone for the rest of the day. Don’t go on and on with it; any further time spent on it is superfluous to the learning process and actually harmful because your mind starts to wander. Do not try it again later that day. During overnight sleep the journey into long term memory continues.
Keep in mind that your aim at this stage is to get clear uncluttered messages to your brain and to ingrain relaxed, efficient movements in your body. Any and all tension in your body will hinder your playing in some way.
You are practising musically, because you are paying attention to the musical aspects separately, but because you are working in a somewhat detached way, the frustration level is kept low.
Repeat procedure with other hand.
Now your first chunk is learned, leave it and go on to the next and however many following chunks you decided you could tackle in same way, (remembering to include an overlap note or two at the end of each chunk into the next bar) Resist the temptation to join up the chunks. By the end of your first practice session you’ve got a few chunks parcelled up and shunting along on some sort of brain conveyor belt on the way to LTM.
Next day session;
Full of hope you go to piano and try to play chunk one and you can’t remember a single note. Doom and despondency set in, all that hard work yesterday …
Don’t despair, this is normal. The parcels have come undone, the conveyor belt was wonky …
What you have to do now is repeat yesterday’s procedure with each bite sized chunk, but it will now take less time, leaving you time to add some more small chunks either from the same section, or a different section of the piece. (You don’t have to work sequentially; you can actually be learning chunks from completely different pieces but depending on how much time you have this will obviously take longer to finish one piece.)
Next day it’s either woo-hoo! I know it, or rinse and repeat the procedure. If you’re a brain dead memorizer like me it can take four or five days, but often the real reason is that I’ve missed a session, or I’ve been tired and not concentrated properly, or I’ve cheated and started to look at the music again. The key principles are consistency, concentration and playing with relaxed movements.
Then suddenly your hands seem to know where to go by themselves and you can start to join up your chunks into longer and longer strings … but again beware of making your joins too long.
When you start to put hands together it can feel very dispiriting as you now have coordination issues to sort out and the whole thing feels completely new. If the piece is relatively simple for you, you can put HT from the start but be sure you’ve got fingering and arm movements that will work at final speed. I start to put HT as soon as a few bars have been memorised HS. If the piece is complex, you can be sure that the HS learning you’ve done will pay off because incorrect movements learned HT are very difficult to change.
With polyphonic music it’s recommended to learn each voice separately, but using the correct fingering for each voice even though this feels weird.
Consistency
This is very important. You need to record each separate bite you practiced every day, e.g. on a chart you make, or as ticks on your score, or in a log book or whatever. I just put a pencil tick over each chunk I’ve worked on that session, and a heart when it’s memorised. Corny!
It’s important to be realistic and not work on ten chunks one day when you’ll only have time to review four or five on the following days. (Not that they’ll get completely forgotten but as a convinced non-memoriser you’ll get discouraged and give up)
Encouraging thoughts
If you think you can, you can…. (Philip Johnstone.)
Practice with a quiet mind. Trust your brain. Cast your mind over what you practised before going to sleep, but without making any huge effort to remember the music. You might be surprised what starts to pop up of its own accord!
