How long does it take the average person to memorize Gershwin's Rhapsody In Blue?
Also, in many cases, it's impossible to say because lots of people memorize as they are learning the music.
Some people do not ?
? just a thought (i dont mem before i play - as such) but how can you know its memorized properly until you play it. I know people who have photographic memory who can look at a score and 'memorize it' but when they play it first they spot gaps/mistakes - so i find it odd for people to say they can 'totally' mem a piece before they play it out - though true MUCH of the work can be done before you begin thumping the old ivories and indeed probably should be done. Memorizing is extremely personal but i dont believe anyone cannot memorize music unless they have somekind of memory deficiency! because it should be a result of good practice technique!
I second this. I'm not sure how you can memorise before starting to play it. I can understand how it is possible but it sound very difficult. Do you have to visualise the notes playing at the piano before even sitting down to play it. If i could learn to that than essentially i could be doing piano work without even having a piano with me.
Some pianists learn the pieces they do in concert in the plane to go to the place their concert is. Yes it's a hard thing to do, but trying to do it before you begin any new pieces could develop this skill enough to be able to do it fairly good in some years.
Bernard do you mean to say that you can only do this with a piece you already know well aurally or have a cd/recording of? As someone pointed out this is not alway the case - as with Rubinstein! It should be noted too that it was a concerto that someone pulled out of at the last min (not his choice) and he was not best please with his performance - although by ordinary standards it was phenominal! Generally your plann of learning a piece sounds well thought out and theres no doubt that disecting a piece (even one youve never heard) gives not only a better understanding of the work but also create an imprint on your memory but whether the skill can indeed be developed to such a degree in MOST individuals to the point that they can avoid practice at the piano completely and learn their music on the way to their lesson and give faultless performances in lesson and concert I fear may be slightly beyond all but a minute percentage of pianists - and for those who can Im sure their teachers know them well enough to spot it and give them hell for just being lazy because they have SO much potential they should be doing even greater things! Granted it works for some but you need more. I would call your plan a process of enculturation - which many students who are enthusiastic about music do naturally (getting score out of library and listening and putting in fingerings etc) which is very useful and may indeed lead to an enhanced memory ability but i would seriously advise a student against a pupil giving a performance from memory in the lesson withhout having done sufficient 'sond' work - you don't know it form memory till you know all the infinite shadings and chord balancings and feeling in your muscles of how you will take this chord etc. this is why it is fatal to change things in the last lesson before a memorized performance because when things come out different to how you 'imagined' you can get in a mess. Simply ... I agree much good work can be done pre play which will pay dividends but would caution that 'succesful' memory IS reliant on 1.Visual, 2.Digital(muscular) AND 3.Auditory senses as well as the 4.analytical processAs I see it your method is excellent in preparing 1.and 4. but may fall down in 4. and fails to connect 2. - 4. which in the way in which I have been taught is the most crucial and indeed the most personal aspect of giving the performance (using your body to make the desired sound)? Maybe if you explain the detailed outworking of your method we would find we agree more closely ?
